Tell me your favorite frugal treats and snacks

I like sour gummy candy, so I substitute dried fruit with sugar and citric acid, and lemon juice to make it stick.

I do the healthy Snicker bar thing where I flatten dates in a tray and cover them with peanut butter and melted chocolate and crushed nuts and put them in the freezer.

Plain chips and homemade salsa sometimes satisfies my cravings for Hot Chip.

"nice cream" with a frozen banana base.

anything else?
