01 - In a small bowl or jar, whisk together olive oil, apple cider vinegar, honey (or maple syrup), Dijon mustard, poppy seeds, salt, and black pepper until well combined and emulsified. Set aside at room temperature.
02 - In a large salad bowl, arrange spinach leaves as the base. Add sliced strawberries, crumbled feta cheese, toasted almonds, and thinly sliced red onion on top.
03 - Drizzle the prepared poppy seed dressing evenly over the salad just before serving. Toss gently using salad servers to coat all ingredients without bruising the spinach or strawberries.
04 - Transfer to individual serving plates or serve family-style from the large bowl. Enjoy as a refreshing starter or light main course while ingredients remain crisp.
