Step 1: Prepare the egg mixture
In a bowl, whisk the eggs, milk, salt, and pepper until smooth. The milk helps create fluffy, rich eggs for the filling.

Step 2: Cook the eggs
In a skillet over medium heat, melt 1 tablespoon of butter or add oil. Pour in the egg mixture and cook, stirring gently until soft and slightly runny. Remove from heat — they’ll finish cooking in the quesadilla.

Step 3: Prepare the fillings
Sauté vegetables or meats in the same pan for 2–3 minutes to enhance flavor and remove moisture.

Step 4: Assemble the quesadilla
Lay a tortilla flat and sprinkle cheese over half. Add scrambled eggs and fillings. Top with more cheese and fold in half. Repeat with remaining tortillas.

Step 5: Cook the quesadilla
Add butter or oil to the skillet. Cook each folded tortilla for 2–3 minutes per side, pressing lightly until golden brown and crispy.

Step 6: Slice and serve
Let rest for 1 minute, then cut into triangles. Serve with salsa, sour cream, or hot sauce.
