I have been making dried shredded chicken for our backpacking meals (add in dried noodles, or instant rice, and seasonings / or dehydrated home made roasted red pepper sauce) for awesome meal on the trail that did NOT cost $10 for 2 people. My Turkey jerky had mixed results, the ground / reformed jerky was better than the whole strips, easier to eat).
I have also made my own cornflakes / bran flakes (not recommended!), and flax granola (recommended) breakfast cereal. I did grow some oats one year, (just enough to try), flattened them with the mallet, and made oatmeal..
Usual suspects for preserves - jam, fruit syrup for pancakes, apricot / orange marmalade, plum jam, etc. Sundried tomatoes in oil. I have canned peaches / pears. I will try a relish recipe this year, too.
Yoghurt, Ricotta, Bread (various types), pierogies, buttermilk, cottage cheese, butter.
Chocolate / vanilla pudding.
Started to freeze summer on-sale produce for the winter -- yellow beans, rutabaga, beets, carrots, cabbage (ick), onions, apple slices and apple sauce -- enough for 26 meals or so, total (not each). I just received a hobby-sized cider press and grinder -- next summer needs to watch out because I aim to try it out.
