1 lb. ground beef
1 packet taco seasoning mix
1 jar taco sauce
1/4 head shredded lettuce
1 lb. shredded cheese

This is a camping recipe. Before you leave home cook the ground beef with the taco seasoning following packet instructions. Freeze meat in a Ziploc bag. At the camp site heat meat over a small fire. Chop tomatoes and shred lettuce if not prepared in advance. Each person should open a Doritos bag carefully. This is their dish, chips should be crushed either before bag is opened or after. Each person should add toppings of choice. If you need refills add Doritos from the large bag, crush and add additional toppings. Using fork, eat directly from the bag.
