In a small bowl, whisk together the olive oil, apple cider vinegar, honey, Dijon mustard, poppy seeds, salt, and pepper until well combined. Set aside.

In a large salad bowl, combine the baby spinach, sliced strawberries, crumbled feta cheese, sliced almonds, and red onion.

Drizzle the dressing over the salad and toss gently to combine, ensuring all ingredients are coated.

Serve immediately for the freshest taste, or refrigerate for up to 30 minutes before serving to allow the flavors to meld.
