This wholesome and satisfying chili has it all: whole grains, protein-rich beans, lots of vegetables, and—most important—great flavor. What more could one want from a chili?
Heat the oil or water in a large pot over medium heat. Add the onion and zucchini, cover, and cook until softened, about 5 minutes. Stir in the garlic and mushrooms and cook for 2 minutes longer, then stir in the chili powder, cumin, oregano, and salt and pepper to taste. Add the quinoa, crushed tomatoes, diced tomatoes with their juices, and broth, and bring to a boil.
