As with the addition of grapes I just though: They have one use currently (hopefully 2 if my endorsed suggestion gets used) and that use seems a bit useless; eating them (brewing them into wine counts as eatig I think) but what if they'd add another bread; Raisin bread, this would be crafted as Banana bread and olive bread but then with Raisins, and Raisins would be made by cooking grapes in a hobbit oven (I know it's weird but this is the closest we come to drying grapes) and you could also eat them but they'd give a bit more saturation then grapes.
