Since you camp all the time, have you considered buying (actually investing in) dehydrated camping meals? All the preparation you need is the entrees and some H2O and a kettle to boil the H20. MREs are even better, as they are fully cooked heat and eats, that all you need is a way to reheat them, such as a camp stove and sometimes a pot to prepare it...otherwise you can sometimes use the packaging itself. They store up to about 5 years. Meals include entrees like chicken, steak, pot roast, pastas and even breakfast favorites. Best of all the food actually tastes great! It's not processed and once rehydrated, you'd think you made it at home.

www.beprepared.com (has both Mountain House and MREs)
Gander Mountain and REI carry these but it's pricey. Sometimes Costco and Sam's Club sell freeze dried camping foods at a great price because it's bulk. Look in-store and online for these foods..click on emergency supplies under the grocery section. Mountain House brand has the best breakfasts (everything from Denver style scrambled eggs to pancakes and real bacon) and they travel well and the pouches store for up to 5 years. The packaging is water tight, floats, and can easily be packed in a backpack and not take up much space.
For anytime camping meals in general, a cheaper alternative are shelf ready foods such as Campbell's Franks n' Beans, Vienna Sausages in the can, canned tuna and sealed packettes of relish and mayo like you get at fast food restaurants to make a spread, already seasoned tuna in foil pouches, soups both dried and canned. Canned Taco meat can be found at stores sometimes. Dried potato hash/shreds are great. There's also Dinty Moore Stew, Swanson Chicken Ala King, and Chung King Chow Mein (all canned goods) or those Heat n' Eats in plastic air sealed plates by Dinty Moore and Hormel that are found on the shelves near their canned counter parts. They have meals like Turkey in Gravy with potatoes, spaghetti and meatballs, and stroganoff. While they are meant to be microwaved, you could always dump them in a pan and heat the contents conventionally. These stay shelf fresh for about a year, but the packaging isn't as hearty as the packaging used for MRE's or the Mountain House. The canned and shelvable heat n' eats are also bulky and may take up too much space or be cumbersome to travel with. But they are alot cheaper than the camping food.
Other ideas include packs of instant Oatmeal, instant cream of wheat, pancake mix that only requires water and syrup that can be stored without refridgeration, canned spam (fries up great and is good in eggs), canned corned beef, and dried eggs and milk (both dried eggs and milk are usually located in the baking section of the grocery store).
