Fried Peanut Butter and Banana Sandwiches

These are my favorite sandwich. Hands down. I could eat one every day.
2 slices of whole wheat bread
peanut butter (we used coconut peanut butter and regular)
banana
butter
cinnamon

slice the banana thin, spread the peanut butter on the bread and assemble sandwich. Cover the outside of the sandwich with butter. Cook on cast iron griddle til golden and crispy. Sprinkle with cinnamon while hot.
