Place the fresh baby spinach in a large mixing bowl.
Add the sliced strawberries, red onion, crumbled feta, and chopped pecans on top.
In a separate bowl, combine the olive oil, apple cider vinegar, honey, poppy seeds, salt, and pepper.
Whisk these ingredients together until they form a smooth dressing.
Pour the dressing over the salad mixture and gently toss everything together until well coated.
Let the salad sit for about 10 minutes to allow the flavors to meld.
Serve chilled or at room temperature.
