Begin by heating a non-stick skillet over medium heat. Add a small knob of butter, approximately one tablespoon, and allow it to melt completely, swirling it around to coat the skillet evenly.

Crack one large egg gently into the skillet and season it with a pinch of salt and pepper. Cook the egg for 4-5 minutes, allowing the white to set while keeping the yolk runny.

In the same skillet, place one flour tortilla and sprinkle half of the shredded cheese generously on top. Let it sit for about 1 minute until the cheese begins to melt slightly. Then, layer the fried eggs on top of the cheese, adding avocado slices, and finally, top with the remaining cheese.

Carefully cover the cheesy filling with the second tortilla, pressing it down gently with a spatula. Cook the quesadilla for 2-3 minutes on the first side until it’s golden brown and crispy.

Once the first side is golden, carefully flip the quesadilla using your spatula. Cook for an additional 2-3 minutes on the other side, ensuring it reaches a deep golden color and the cheese is perfectly melted.

Remove the quesadilla from the skillet and allow it to cool slightly before slicing it into wedges. Serve immediately while hot, pairing it with salsa, sour cream, or fresh herbs.
