I make a big pot of spaghetti sauce (or at least I did when I had freezer space) and I use 1 lb of ground beef, celery, carrots, mushrooms, onions and garlic - zucchini if it's in season. I just grate the carrots and zucchini. Lots of herbs and enough tomatoes to fill the pot, some tomato paste and let simmer for a good while. That's good for at least 5-6 meals and is generally my fast meal as I can defrost/heat the sauce in the microwave while the water for the pasta is boiling.
for chili, I use at least three different kinds of beans (usually kidney, chick and random choice) and lots of them, a pound of gr. beef, celery, mushrooms, frozen corn, peppers (of whatever colour) and tomatoes. It makes a big pot that is enough for at least 3 good meals for my family of 4 that includes an active teenage boy.
You can also make soups with the same ingredients - just change your seasonings. Have beef, chicken, veg stock on hand - I use the Knorr liquid concentrate. You can make soups out of just about anything. Barley is probably my most favourite soup filler. It is cheap and holds its form really well - doesn't get soggy like pasta or rice - and freezes well. It's also good for pilafs.
Another good tip for bread is you can make your own. Use a small amount of yeast, mix it up and let it sit in the bread pan overnight for a long slow rise. Bake up in the morning and you have fantastic bread. You don't have to knead it for a long time either because the yeast does the work for you. You can make buns as well with that method. Just form the buns in the morning, let them sit for a bit and then bake.
My favourite no work meal is cheap cuts of meat in the slow cooker. i buy whole chickens when they're on sale and throw them in with potatoes, onions, carrots (or whatever else i have on hand.) Same for beef brisket.
I always keep potatoes, onions, garlic and a good supply of seasonings and herbs on hand. I like frozen veg like peas, corn and beans. You can freeze them yourself by blanching - tossing them into boiling water for a few minutes and then plunging them in ice-cold water to stop the cooking process. Then the veg aren't soggy and you can cook them up pretty quickly just by steaming.
Apples freeze well in any form. I make applesauce or peel and cut the apples for apple crisps or pies.
