Combine dressing: In a small bowl or a jar with a tight-fitting lid, whisk (or shake) the olive oil, white wine vinegar, honey, poppy seeds, salt, and pepper until well combined.
Assemble salad base: Place the spinach leaves in a large salad bowl. Top with the sliced strawberries, red onion, feta cheese, and toasted almonds.
Dress & toss: Drizzle the poppy seed dressing over the salad just before serving. Toss gently to coat all ingredients evenly.
Serve fresh: Enjoy immediately for the best texture and flavour.
