Black Bean Quinoa BurgersBlack beans are a great source of plant-based protein, fiber, and potassium. For a vegetarian mama like myself, beans and quinoa make up a large source of my daily protein. I love adding quinoa to meals because it's a superfood rich in protein, fiber, vitamins, and minerals. Complete with hidden spinach and bell peppers, this vegetarian burger is a great meal option for little kids and adults alike!
