Firstly you butter 2 slices of bread.
then slice some cheese and 1 banana put banana and cheese slices onto the unbuttered side of first slice of bread then place into a hot pan or onto a grill put the second piece of bread buttered side facing up on top and cook each side till golden brown......be sure not too use summoned bread as this sometimes dissapears leaving a big mess in ya pan.
This does sound yuk but i assure you once you try it you will never want a ham and cheese again.
