when I buy fresh fruit, I always prepare it, (peel and dice) then put some in the fridge, some in serving size bags in the freezer. I use the frozen servings in lunch boxes, they keep the food cool and thaw by lunch time. For snacks, I only let them partially thaw, enough for comfortable eating.
These are expecially good for hot weather snacks or refreshers at work like construction where you need extra liquid and cooling.
Melons like watermelon or cantelope are great this way Use the more solid fruits as ones like oranges tend to get muchy. A great way to get vitamins, liguid, fiber, treats, healthy and cool off at the same time
