Freezing fruits

I am not a fruit person, but having children requires buying fruits all the time. When the fruits are not all eaten in one week, I stick it in the freezer to preserve than letting it rot to waste. I slice the strawberries and peel the bananas before I put it in freezer bags - I buy ziplocs from the dollar store, they work perfectly fine too, 16 pieces of gallon size bags for a dollar only! Grocery stores are selling frozen fruits. I never buy it. I freeze my own fruits! From grapes, to bananas, to berries. Then, we just take it out to make smoothies!
