If we are canoe or car camping, we have a cooler that will usually be stocked with eggs, some sort of breakfast meat and hash brown potatoes. We'll usually have some chicken, pork chops, burgers, or some sort of sausage (kielbasi, brats, knockwurst, Italian, etc) for dinner along with sides like pre made mashed potatoes, fresh corn, rice. We'll have cold cuts and bread to make sandwiches. Maybe some pasta and sauce.
Backpacking, if only for one night we may have any of the above and freeze it. By dinner time the meat is thawed and ready for cooking. For multiple day trips, lots of instant mashed potatoes, Minute Rice, angel hair pasta. That along with cheeses, dehydrated meats, those foil packets of fish steaks, canned seafood along with various spices and dehydrated pepper, onions and fresh garlic etc can be combined into some really light weight and satisfying meals
For breakfast, oatmeal, powdered eggs (actually pretty good if you add some cheese and maybe a little reconstituted dried onion and/or peppers), those individual foil packets of Spam, pre cooked bacon, etc.
GORP, jerky, cheddar cheese, canned sardines, peanut butter, oysters, crackers (Triscuits, Weat Thins) etc for lunch on the trail.
