01 - Heat olive oil in a large skillet over medium-high heat. Add the sliced beef, salt, black pepper, and smoked paprika. Sauté for 2 minutes until the beef begins to brown.
02 - Add brown sugar or honey, soy sauce, minced garlic, and sliced red onion to the skillet. Cook, stirring continuously, until the beef is fully browned and the onions have softened, about 4 to 5 minutes. Remove from heat and set aside.
03 - Wipe the skillet clean and return it to medium heat. Place one flour tortilla in the skillet. Sprinkle half of the mozzarella and cheddar blend evenly over one half of the tortilla.
04 - Distribute a quarter of the beef mixture, sliced red bell pepper, and corn kernels over the cheese. Fold the tortilla in half, pressing gently to enclose the filling.
05 - Cook the quesadilla for 2 to 3 minutes per side, pressing gently with a spatula, until the exterior is golden brown and the cheese has fully melted.
06 - Remove the finished quesadilla and set aside. Repeat the assembly and cooking process with the remaining tortillas and fillings.
07 - Cut each quesadilla into wedges. Serve warm accompanied by sour cream, fresh cilantro, and lime wedges if desired.
