In a bowl, mix your cheese with any additional fillings like chicken or vegetables.

Place your non-stick skillet over medium heat.

Lay one tortilla in the skillet and sprinkle half of the cheese mixture over it.

Layer on your chicken or veggies evenly if using.

Sprinkle the remaining cheese on top of the filling, then place a second tortilla over everything.

Cook for about 3-4 minutes, or until the bottom tortilla is golden brown.

Carefully flip the quesadilla using a spatula and cook for another 3-4 minutes until the other side is crispy and the cheese is melted.

Remove the quesadilla from the skillet and let it cool for a minute.

Slice into wedges and serve with your favorite salsa or guacamole.
