Made a fruit salad of mango, fresh cherries (halved), blueberries, one peach and some green grapes. Think I cut too much for 2 people and don't want it to get rotten. Wondering if this concoction could be turned into a crisp or crumble and would I need to remove the grapes? Do any of these fruits NOT WORK in a crisp? Finally, best, easiest recipe for crisp? Whew! Thanks all.
