If you think you aren’t going to eat all of your spinach before it goes bad, puree it! Add a few strawberries or watermelon with it and blend on the chop setting in your blender. Pour into ice trays and freeze. Do the same with your fruit before it goes bad, too! Puree strawberries, raspberries, blueberries, blackberries, kiwi, cantaloupe, watermelon, mangoes, pineapple, peaches ... you get where I’m going with this.
If you have fruit that *might* go bad, go ahead and puree it! You can freeze your fruit without blending it, too. Just wash it and place on a cookie sheet and freeze. Once frozen solid, place in individual containers or zip-top bags. Just grab a couple each morning, and you are good to go!
