Whisk together all of the ingredients (Greek yogurt, milk, honey, dijon, and poppy seeds) together in a small bowl. Store in an airtight container in the fridge until ready to use.
⅓ cup plain Greek yogurt, ¼ cup milk, 1 tablespoon honey, 1 teaspoon Dijon mustard, 1 tablespoon poppy seeds
For the Salad
Add the spinach, strawberries, walnuts, raspberries, blueberries, and goat cheese to a large bowl. Drizzle over as much dressing as you like (I usually use about ½-¾ of it) and toss to combine.
6 ounces fresh baby spinach, ½ cup strawberries, ⅓ cup roasted salted walnuts, ¼ cup raspberries, ¼ cup blueberries, 2 ounces goat cheese
Serve immediately.
Notes
Storage: I do not recommend storing this salad once dressed, as the spinach will wilt quickly. Store the salad and the dressing in separate airtight containers in the refrigerator for up to 3 days.
