Folded method: Instead of a full quesadilla, add cheese to one half of a single tortilla and fold it over — this half-moon shape is easier to flip and ideal for cooking one serving at a time over a campfire. Variations: Add leftover grilled chicken, black beans, sliced jalapeños, roasted peppers, or caramelized onions along with the cheese for a heartier meal. Storage: Campfire quesadillas are best eaten fresh and hot. If you have leftovers, store in an airtight container in a cooler or refrigerator for up to 1 day. Reheat in a dry skillet over medium heat for 1–2 minutes per side to restore crispiness — avoid the microwave, which makes them soft and chewy. Cheese tip: Always shred cheese fresh from a block. Pre-shredded cheese contains anti-caking powder that prevents smooth melting.
