These cheesy quesadillas are a great snack or light meal. Pulse some onions and garlic in a food processor, then brown the ground beef in a skillet. Add the onion mixture, cumin, chili powder, and any other desired seasonings, and cook until the flavors meld together. Spoon the beef mixture onto tortillas, top with shredded cheese, and fold over to seal. Cook in a skillet until the cheese is melted and the tortillas are crispy.
