I like to make fruit bowls. I get two different types of berries (I get fresh) one or two cans of diced pineapple in 100% juice (usually costs me a dollar) and a jar or can of mandarin oranges (100% juice) mix them all I. A giant bowl, separate into several small Tupperware containers, and snack away for at least a week. The citric acid from the pineapple keeps the fruit fresher, longer. It costs me usually less than twelve dollars, and I get at least six (with one can of pineapple) bowls.
And you'll hear this a lot: eat in season, freeze extras
