Some samples are:
Easy Breakfast Burritos Recipe: These can be made on a Sunday morning and all you need is a pot of boiling water. NO CLEAN UP!
Dutch Oven Sausage & Egg Breakfast Recipe: This is a good Saturday morning breakfast that can be done using only the Dutch Oven. You can cook with the dutch oven directly on the cook stoves so you don’t need to wait for coals. It is just like a cast iron skillet, only with taller sides. If you warm some tortillas on the flipped over lid, you can use this for a breakfast burrito.
Shepperd’s Pie Recipe: You could substitute any other vegetables in this one (peas, green beans, carrots). You also don’t really need to line the dutch oven with foil. It might be hard to brown the ground beef with the foil in the oven. You can adjust the amount of ground beef for the amount of people and add more vegetable if needed. This also only uses a a couple of pans for cooking.
This is another really good site for recipes: Byron’s Dutch Oven Recipes
Here is one from that site that looks fairly easy to do:
Easy Cheesy Meat And Potatoes: If you don’t like mushrooms, just substitute cream of mushroom soup instead. You could mix up the sauce and put it in a ziplock ahead of time to simplify preparation at camp.
