This is actually one of the 'party finger food' recipes. Since I wasn't planning a party and happened to have the ingredients on hand, I made it anyway.
Finally, you just bung your bacon-wrapped bananas under the grill, turn them a few minutes later and grill the other side, then you're done: sweet, salty morsels once again utilising that delicious banana and bacon combination.
These may be pretty tasty, but they have to be served warm, so if your're going to do these for party finger food, you'd need to spend a few minutes in the kitchen doing the grilling bit. I expect you could do the banana-wrapping bit in advance, but how far in advance, I'm not sure. I'd say best keep the time between wrapping and grilling as short as possible.
