Cook the bacon, then crumble it. (Microwave, skillet or bake it in the oven.)
Preheat the oven to 350 if you plan to bake your quesadillas.
Scramble the eggs. Season with garlic powder, cumin and a little salt and pepper. (Don't add too much salt, as the bacon will bring more saltiness.)
Lay out 4 tortillas on a flat surface or greased baking sheet and top with pinchful of shreddedcheese, scrambled eggs, crumbled bacon, distributed evenly among the tortillas. Add a pinchful more cheese and then top with the remaining 4 tortillas.
Bake in the preheated oven for 15 minutes, flipping once after about 8-9 minutes. You can also add some oil to a skillet and heat/brown/saute them, flipping carefully.
Cut with a pizza cutter into slices and serve Breakfast Quesadillas with salsa, avocado or fruit.
