Bean burgers are a favorite way for our family to use up extra rice or quinoa, and make a FAST, vegetarian meal. Make two batches at once and serve the next day or pack for lunch. Even with a standard bun, these are SUPER cheap, at just under 1 dollar per serving. Top with whatever burger toppings your family enjoys. If you are eating gluten-free use certified gluten free oats, and your favorite gluten-free bun or wrap. This can also be served on top of a salad.
