Whisk together eggs a medium bowl.
Melt 1 tablespoon butter in a skillet over medium heat. Add the eggs and cook, undisturbed, until a thin layer of cooked egg appears around the edge of the skillet. Using a rubber spatula gently move the eggs around the skillet until they are nice and fluffy. They will still be glossy in color.
Once your eggs are done, remove them from the heat and get ready to add them to your flour tortillas.
Add 1/2 tablespoon of butter to a skillet over medium heat – swirling around the pan until melted.
Next, add 1 tortilla to the pan ( I use the burrito size) and top with a sprinkle of melted cheese.
Then, add your eggs to the tortilla evenly and top with the remaining cheese.
Cook the bottom tortilla until lightly brown, then flipping over and browning the other side evenly. Add 1/2 tbsp of butter if needed.
Once it’s brown, remove the quesadilla to a cutting board and allow to rest for 1-2 minutes. Cut into triangles and serve with salsa if desired!
