You've probably already figured that we like to keep beach snacks simple. Nobody wants to put in a lot of work in advance, and nobody wants to deal with containers of food that are going to be magnets for the ever-present sand.
But a fruit salad doesn't have to require a lot of work, and it sure provides a refreshing and healthy treat.
Mix up slices or chunks of pineapple, kiwi, mango, some seedless grapes or whatever else you find. Sweet cherries can be good, too. Then stir in some frozen fruits. Frozen blueberries, strawberries and slices of peach work well here. You may luck into finding some of these fruits fresh and in season. You can freeze those easily. With blueberries, for example, all you have to do is wash them, pick off any bits of stem, put them in a plastic bag and pop them in the freezer.
Pack the salad into small containers and keep those in the cooler or an insulated bag, if you have one. If not, the frozen fruit you mixed in will help keep the whole salad cool for a while.
Remember the spoons, and enjoy!
