To create the best ever breakfast quesadilla, follow these simple steps:

1. Prep Ingredients: Gather all your ingredients. Dice vegetables and cook the sausage or bacon if using.
2. Whisk Eggs: In a medium bowl, whisk together the eggs, salt, and pepper until frothy.
3. Cook Vegetables: Heat a non-stick skillet over medium heat. Add a bit of butter or oil, then sauté the diced vegetables until soft.
4. Add Eggs: Pour the whisked eggs into the skillet with the cooked vegetables. Stir gently until the eggs are scrambled and cooked through.
5. Assemble Quesadilla: On half of each tortilla, layer a portion of the scrambled eggs, cheese, and your choice of meat or additional fillings. Fold the tortillas in half to cover the filling.
6. Cook Quesadilla: In the same skillet, add more butter or oil if needed. Place the folded quesadilla in the skillet, cooking for about 2-3 minutes on each side until golden brown and crispy.
7. Repeat: Continue with the remaining tortillas until all quesadillas are cooked.
8. Slice Quesadillas: Remove from heat and let cool slightly. Use a sharp knife to slice each quesadilla into wedges.
9. Serve: Plate the quesadilla wedges and serve warm, with salsa or sour cream if desired.

These straightforward steps will guide you to create a delightful breakfast that everyone will enjoy!
