You could also try this with little unripe finger-sized bananas, for an unusual appetizer offering.
6 large green bananas or plantains
8 oz ground beef or turkey
1 onion, chopped
1 egg, beaten
Without peeling, cut the bananas into halves along their length. Scoop out the flesh with a spoon. Leave the peel boat-shaped.
Grate or mince the banana flesh. Mix the meat, onion, and salt with the banana. Add the beaten egg to bind it. Put the mixture back into the banana peels. Tie the halves together with string.
Steam for 25 minutes or bake at 350 F for 45 minutes.
