Heat a medium sized skilled over medium heat.
Place one tortilla into the skillet. Add a layer of cheese, then a layer of scrambled eggs, then a layer of chopped bacon. Top with a final layer of shredded cheese.
Place a second tortilla on top of the egg and cheese layers. Cook until the bottom layer tortilla is golden brown. With a spatula, carefully flip the quesadilla. Cook the remaining side until golden brown.
Put the quesadilla onto a cutting board and let cool for 3-4 minutes, then quarter. Serve warm with a side of salsa and sour cream.
