Apple Crisp with Rolled Oats

Instructions:

1. At home: Combine the oats, flour, brown sugar, and salt in a sealable bag.
2. At home: Toss sliced apples with lemon juice, cinnamon, and brown sugar in a separate container. Store both components chilled in a cooler.
3. At the campfire: Pour the apple mixture into a 12-inch cast iron skillet or divide evenly into 6 double-layered foil packets.
4. Using fingers, rub the cold cubed butter into the dry oat mixture until it forms pea-sized clumps.
5. Scatter the crumble evenly over the apples, ensuring the edges are well-covered.
6. If using a skillet, place on a grill grate over medium coals and cover with a lid or foil for 20-25 minutes. If using foil packets, place directly on medium coals for 15-20 minutes.
7. Remove from heat when apple juices are bubbling up the sides and the topping is mahogany-colored and golden-brown.
