Kevin, what do you eat at home? Do you actually cook at home? (I know, a blunt, but often fatal question, because if you don't cook at home, how can you expect to cook on tour) What's the simplest dishes you cook at home?
There are all sorts of possibilities. Will you be riding past markets with fresh vegetables and butcheries (does the US still have butchers?)? You can make up stews without much trouble. The old standbys are still noodles or pastas with sauces with canned tuna or chicken mixed in... or seasoned sausages. Rice is another useful stomach filler that can be flavoured with anything and is high in cycling energy. Take some sachets of flavourings -- curries and stock cubes or powders. Crispy bread rolls with ham and cheese and tomato can make a meal in themselves.
I've found TVP when cooking at home to be a good substitute for mincemeat. It's light, reconstitutes quickly, and is filling, and will absorb the taste of whatever is cooked with it.
It truly does depend on the circumstances of your travels.
