For a vegetarian option, try these black bean and quinoa air fryer burgers. Black beans and quinoa are combined with onions, garlic, and spices to create a hearty and protein-packed patty. The air fryer gives them a crispy exterior while keeping the inside moist and flavorful. Serve on a whole wheat bun with avocado slices, lettuce, and salsa for a delicious and nutritious meatless meal.
