What To Do
1 Chiffonade the spinach. Thinly slice the red onion, tomatoes, and black olives.
2 On a plate, place a tortilla. Sprinkle with your desired quantities of spinach, red onion, red pepper, black olives, mozzarella, feta, oregano, and red pepper flakes (if using). Be careful not to overload.
3 Heat a large non-stick skillet over medium heat for a few minutes. Place the loaded tortilla on the griddle and place another tortilla on top. Cook until browned on the bottom, then flip and cook until browned on the other side (a few minutes per side).
Remove the tortilla and cut into wedges with a pizza cutter. If making several quesadillas at once, you can keep them warm in a 300°F oven.
