What’s in this Salad?

Quinoa has become a popular rice alternative thanks to its high fiber and protein content. It’s a great stand-in for pasta or rice when you want a nutritious carbohydrate base.

ingredients for the grilled vegetable quinoa salad

Quinoa – Rinse it before cooking. Any brand works; use what you prefer.

Summer Veggies – Zucchini, red bell pepper, and red onion are used here. You can swap or add yellow squash, portobello mushrooms, or Vidalia onion depending on what’s in season.

Balsamic Vinegar – Works as both a marinade for the vegetables and part of the vinaigrette. If you prefer, red wine vinegar can be substituted.

Mozzarella – Fresh mozzarella pearls are ideal. If unavailable, chop fresh mozzarella into bite-sized pieces; avoid shredded mozzarella, which tends to blend in too much.
