I found this recipe in a book called Favorite Family Meals. I made it for the kids awhile ago(probably a year or two). They thought they were so fun, they still talk about them. I think next time I'll try them with cheese cubes.
Smooth peanut butter
1 red apple, cored and sliced into eighths
Squeeze of lemon juice
Miniature marshmallows or cheese cubes
Spread peanut butter on one side of each apple slice (squeeze a little lemon juice over apple slice if not serving immediately). Place four miniature marshmallows on one apple slice and then lay another apple slice, peanut butter side down, on top.
