Cook the ground beef in a skillet over medium heat, breaking it up with a spoon until browned.
Season the beef with salt, pepper, garlic powder, and onion powder, then drain any excess fat.
Lay out 4 tortillas and sprinkle each with a layer of shredded cheese.
Distribute the cooked beef evenly over the cheese on each tortilla.
Add any optional toppings like diced onions or pickles over the beef.
Top each with more shredded cheese and place another tortilla on top to form a quesadilla.
Heat a skillet or griddle over medium heat and lightly butter or oil the surface.
Grill each assembled quesadilla for 2 to 3 minutes per side, pressing gently, until cheese melts and tortillas are golden and crisp.
Cut the quesadillas into wedges and serve warm with ketchup, mustard, or your favorite burger sauces.
