Prepare the dressing: In a small bowl or jar, whisk together the olive oil, apple cider vinegar, honey, poppy seeds, Dijon mustard, salt, and pepper until well combined. Set aside.
Assemble the salad: In a large salad bowl, combine the fresh spinach, sliced strawberries, diced avocado, and thinly sliced red onion.
Add the toasted nuts (if using) to the salad bowl.
Drizzle the prepared poppyseed dressing over the salad.
Gently toss the salad to coat all ingredients with the dressing.
Serve immediately and enjoy!
Notes
For an added protein boost, consider adding grilled chicken or shrimp. This salad is also delicious with a sprinkle of feta cheese.
