Creating a delicious Spinach Berry Salad is straightforward if you follow these simple steps:

1. Wash and Dry Spinach: Rinse the baby spinach leaves under cold water, then spin them dry in a salad spinner or pat gently with a towel.

2. Prepare the Berries: Slice the strawberries and wash the blueberries. Set them aside.

3. Chop Optional Ingredients: If you’re using walnuts, feta cheese, or red onions, chop them according to your preference.

4. Combine Spinach and Berries: In a large bowl, combine the fresh spinach, sliced strawberries, and blueberries.

5. Add Optional Ingredients: Gently mix in walnuts and feta cheese if desired. They add flavor and texture to the salad.

6. Add Dressing: Drizzle the balsamic vinaigrette over the salad. Use just enough to enhance the flavors without drowning the ingredients.

7. Toss Together: Gently toss everything together to ensure all ingredients are coated evenly with dressing.

8. Serve Immediately: For the best taste and texture, serve the salad right away.
