Try one of these three creative ways to serve quesadillas from chef Sara Foster's cookbook, "Sara Foster's Casual Cooking."
Lay tortillas on a flat work surface and place desired fillings over half of each tortilla. Fold tortillas in half to enclose filling.
Lightly coat a cast-iron skillet or grill pan with olive oil and place over medium-high heat. Place quesadillas in skillet or on grill, working in batches if necessary, and cook, turning once, until cheese is melted and tortillas are golden brown, about 2 minutes per side.
Transfer quesadillas to a baking sheet and place in oven to keep warm. Repeat process with remaining ingredients, adding more oil to the grill or skillet as needed. Cut quesadillas into wedges and serve warm with desired garnishes.
