I have started going to Sam's Club for things with a long shelf life. Tomatoes in sauce, paste and diced form I can use for so many things. I get bread flour, all purpose and yeast (I make bread a lot).
They have Sargento cheese that is very good. I have one of those food saver things to seal it up in smaller packages. That is great for the loaves of mozzarella too I cut it into blocks and shred it with the food processor. Pepperoni can be divided and sealed too.
I like the big bags of frozen broccoli, corn and the asian mix veggies too.
My husband laughs at me because we don't really need to take it that far with the budget cuts but I like trying to see how far I can go with a smaller amount of money. Then there is more to spend on other stuff. You know makeup and shoes for me ... Movies for the kids. The GOOD stuff.
