How about simply flavoring the bananas? There's butter, whipped cream, peanut butter, chocolate, ice cream (banana shake!), mint. There's all kinds of cheese, savory herbs and spices. Try eating bananas with sticky rice. You could make banana sushi. Bananas can be spiced with sugar and cinnamon and thrown into a tortilla for a make-shift crepe. My favorite is sliced bananas rolled in honey, covered with crushed peanuts.
Man, I love bananas.
