Meat and Cheese Quesadillas

Preparation

In a bowl, combine the shredded beef with the chopped onion and cilantro. Season with salt and black pepper to taste.
Heat a skillet or griddle over medium heat and lightly grease it with oil or butter.
Warm the corn tortillas for a few seconds so they become flexible.
Place one tortilla on the skillet. Add a layer of cheese, a generous spoonful of the beef mixture, and a little more cheese on top.
Fold the tortilla in half and cook for 2–3 minutes per side, until golden and crispy with the cheese fully melted.
Repeat with the remaining tortillas and filling.
Serve hot with lemon halves and your favorite red or green salsa.
