Simple to make, very quick and kid friendly. Could be a snack or lunch.
Here's what you need:
Fuji apple, thinly sliced
Pita bread (cut in half)
Sliced or shredded cheddar cheese (sharp as you like it)
Put the apple slices and cheese in the pita. Melt some butter in a pan. When it's hot enough but not (brown and burning) place your pitas in the pan and flip after a couple minutes.
