Recipe Info

  • Prep Time: 15 minutes
  • Cook Time: 0 minutes
  • Total Time: 15 minutes
  • Yield: 4 servings

Ingredients

For the Salad:

  • 5 ounces (about 5-6 cups) fresh baby spinach
  • 1 cup mixed berries (strawberries, blueberries, raspberries, blackberries), washed and hulled/sliced if large
  • 1 ripe avocado, pitted, peeled, and sliced or diced
  • 1/4 cup thinly sliced red onion
  • 1/4 cup toasted pecans or walnuts, roughly chopped

For the Lemon Poppy Seed Dressing:

  • 1/4 cup extra virgin olive oil
  • 3 tablespoons fresh lemon juice (from 1-2 lemons)
  • 1 tablespoon maple syrup (or agave nectar)
  • 1 teaspoon Dijon mustard
  • 1 teaspoon poppy seeds
  • 1/4 teaspoon sea salt
  • 1/8 teaspoon black pepper

Step-by-Step Instructions

  1. Prepare the Dressing: In a small bowl or jar with a tight-fitting lid, combine the olive oil, lemon juice, maple syrup, Dijon mustard, poppy seeds, sea salt, and black pepper. Whisk vigorously or shake well until the dressing is fully emulsified and creamy. Taste and adjust seasonings if needed. Set aside.
  2. Wash and Dry Spinach: Place the baby spinach in a large salad spinner or colander. Rinse thoroughly under cold water. Spin dry very well, or gently pat dry with a clean kitchen towel. Excess water can dilute the dressing.
  3. Prepare Remaining Salad Ingredients: Wash and prepare your mixed berries. If using strawberries, hull and slice them. Pit, peel, and slice or dice the avocado. Thinly slice the red onion. Roughly chop the toasted pecans or walnuts.
  4. Assemble the Salad: In a large salad bowl, gently combine the dried spinach, mixed berries, sliced avocado, and red onion.
  5. Dress and Serve: Just before serving, drizzle the prepared lemon poppy seed dressing over the salad. Toss gently to ensure all ingredients are lightly coated. Sprinkle with the toasted pecans or walnuts. Serve immediately and enjoy!

Pro Tips for Success

  • Thoroughly Dry Your Greens: This is crucial for a non-watery salad. Use a salad spinner for best results. If you don’t have one, lay the washed spinach on clean kitchen towels and gently roll them up to absorb moisture.
  • Toast Your Nuts: A quick toast in a dry skillet over medium-low heat for 3-5 minutes (or in the oven at 350°F/175°C for 5-7 minutes) brings out the natural oils and enhances the flavor and crunch of pecans or walnuts. Let them cool completely before adding to the salad.
  • Emulsify the Dressing Well: Whisking or shaking the dressing vigorously ensures that the oil and lemon juice combine properly, creating a smooth, creamy texture that coats the salad beautifully. If it separates, just give it another good shake or whisk.
  • Dress Just Before Serving: To prevent the spinach from wilting and the berries from becoming soggy, always add the dressing right before you plan to eat. This keeps the salad fresh and crisp.

Variations & Substitutions

  • Greens Swap: While spinach is wonderful, feel free to use mixed greens, spring mix, or even a tender butter lettuce.
  • Fruit Fun: Any combination of fresh berries works beautifully. You could also add sliced peaches, nectarines, or even segments of orange for a different fruity twist.
  • Nut & Seed Alternatives: If pecans aren’t your favorite, try toasted almonds, cashews, or pumpkin seeds (pepitas) for a similar crunch.
  • Boost the Protein: For a more substantial meal, add a cup of cooked chickpeas, white beans, grilled tofu, or tempeh. Roasted edamame also makes a great addition.
  • Spice It Up: A tiny pinch of red pepper flakes in the dressing can add a subtle kick if you enjoy a bit of heat.
  • Herbaceous Touch: Fresh mint or basil, finely chopped and sprinkled over the salad, can add an extra layer of refreshing flavor.

Serving Suggestions

This Summer Berry & Spinach Salad is incredibly versatile and perfect for a variety of occasions. It shines as a light and refreshing lunch on its own, especially on a warm day. It also makes an excellent side dish for a casual dinner. Consider serving it alongside:

  • Grilled plant-based chicken or veggie burgers.
  • A simple bowl of lentil soup or a light gazpacho.
  • Crusty whole-grain bread or garlic bread.
  • Quinoa or couscous for a heartier meal.
  • As part of a brunch spread with other light dishes.

Storage & Reheating

  • Fridge Storage: This salad is best enjoyed fresh. If you anticipate leftovers or want to prep ahead, store the undressed salad components (spinach, berries, avocado, onion, nuts) separately in airtight containers in the refrigerator. Store the dressing in a separate airtight jar.
  • How Long It Stays Fresh: Undressed salad components will stay fresh for 2-3 days. Once dressed, the salad is best consumed within an hour or two, as the spinach can wilt and the berries can soften.
  • Freezer Storage: This salad is not suitable for freezing. The fresh greens and berries will not hold their texture well after thawing.

Frequently Asked Questions

Can I make this salad ahead of time for meal prep?

Yes, you can! Prepare the dressing and store it in an airtight jar in the refrigerator for up to 5 days. Wash and dry the spinach, slice the red onion, and toast the nuts, storing each in separate containers. Slice the avocado and combine the berries just before serving to maintain freshness and prevent browning or sogginess.

What if I don’t have all the berries listed?

No problem at all! This salad is very flexible. Use any single type of berry you have on hand, or a mix of two or three. Fresh cherries (pitted and halved) or even grapes (halved) would also be delicious additions.

How can I make this salad more filling to serve as a main course?

To transform this into a hearty main, consider adding a source of plant-based protein. Roasted chickpeas, grilled or pan-fried tofu cubes, cooked quinoa, or even a scoop of white beans would all be excellent choices to boost the satiety factor.
