Creating this Quinoa Salad with Spinach, Strawberries, and Blueberries is simple if you follow these steps:

1. Rinse the Quinoa: Rinse quinoa under cold water in a fine mesh strainer. This removes any bitterness.
2. Cook the Quinoa: In a medium saucepan, combine rinsed quinoa and water or vegetable broth. Bring to a boil, then reduce to low heat. Cover and simmer for about 15 minutes or until the quinoa is fluffy.
3. Prepare Ingredients: While the quinoa cooks, wash and chop the spinach, strawberries, and red onion.
4. Mix Dressing: In a small bowl, whisk together the olive oil, balsamic vinegar, salt, and pepper until well combined.
5. Combine Ingredients: In a large mixing bowl, combine cooked quinoa, spinach, strawberries, blueberries, and red onion.
6. Add Dressing: Pour the dressing over the quinoa salad mixture. Toss gently until all ingredients are well combined.
7. Add Cheese and Nuts: If using feta cheese and almonds, add them now and mix lightly.
8. Taste and Adjust: Taste the salad and adjust seasoning with more salt and pepper if needed.
9. Chill (Optional): If desired, refrigerate the salad for 20-30 minutes before serving. This helps the flavors meld together.
10. Serve: Transfer to a serving bowl or dish, and it’s ready to enjoy!
