Smoothies, if you have blender. Get some frozen fruit, some yogurt (or milk or cream,) maybe some water to help it blend, mix in chunks of ice if you want that, too.

Any frozen fruit will do, but I particularly like strawberry or mango with a not-frozen banana tossed in. another more dessert-y smoothie was raspberries with chocolate sauce.

you can also add things like kale or whatever greens, if you want the fiber and stuff.
