While I have yet to break in our TT kitchen, I have done A LOT of camp cooking. I spent 3 summers cooking for 60+ treeplanters in a remodeled semi truck trailer, summers working in kids camps, as well as do plenty of cooking in our cabin over propane and wood cookstove. One of our staples at the cabin is bannock. Very simple, very easy and can be changed up for variety. All you need is a cast iron frying pan, flour, baking powder, salt, water and oil. There are lots of recipes on the internet, but I've found mine is still my favourite. In a bowl, while your frying pan is heating up with a generous coating of oil in it, mix 2 cups of flour (white or a mix of white and brown), 1 tbsp. of baking powder and a tsp. of salt. Stir together then add water stirring until it is a sticky dough. You can either put the whole thing in the pan for one big bannock, or spoon it in as biscuit sized. Dip a fork in the hot oil and spread the dough out to about an inch thick. Keep your heat low and allow the bannock to brown before flipping it over. Delicious served with lots of butter! You can add things like cinnamon, sugar and raisins for a sweet bannock, or Parmesan cheese, herbs...whatever you like! I will usually make a big batch to have with dinner, and then have leftovers for making 'sandwiches' and snacks.
I have a blog where I did a tutorial on making bannock if you are interested.
