Something else about buying in bulk and freezing ahead.
Some cheeses freeze better than others. Very curdy cheeses freeze well but don't shred well after being frozen. Sometimes you can crumble them to get the same effect though. Moderately curdy cheeses don't crumble or shred well after freezing. Mozzarella seems to be the best freeze and shred cheese.
If you buy meats cheaply, sometimes it is cheaper to get on sale roasts than to get stew meat. Chop it up and package it in sensible sized packages and you'll use it more efficiently.
If you buy stew meat, grab the kitchen shears, and cut the meat pieces smaller before you use them. 1/2" cubes go further than 1" cubes. Smaller than that and you can't get a good enough bite to satisfy, but about that size means you can make a soup and get a bit of meat in every bite, so it feels more satisfying with a little less meat in the pot.
Same with ham - don't dice too tiny, but do dice about half inch dices. Enough to taste it really well, but small enough to go a long way.
Go to your local Game Warden also, and find out if you can be put on a list for confiscated game. Some areas require that you be financially disadvantaged, some do not, so ask about the rules. But if you can get on that list, you may end up with a little extra wild game in the fall - of course, that means they'll come dump it unexpectedly, and you have to process it when you get it, but we usually get a fair amount of game in the fall just because we are home and always say, "Sure, bring it over".
And no, homemade pizza is NEVER a cheap as frozen, but is usually less expensive than take-out. But nutritionally it is Real Food. It is a very good balance of carbs, proteins, fats, and even veggies if you build it that way. You can choose to have a chemical free pizza if you want, and you can't put a price on that (frozen pizzas don't just have the chemicals in the sauce, they also have preservatives in the dough - plus they are very weak on real nutrition). Pizza got a bad rap because of what commercial pizza is, not because of what homemade pizza can be, meat, cheese, sauce, dough, and all.
Look for culprits in your grocery list like Cold Cereal, too. Lots of less expensive options to avoid that, and it is costly in more ways than one, even if you get the "healthy" stuff.
