What can you cook with a waffle iron (besides waffles)?

I recently saw a recipe in Southwest Airlines magazine for making chocolate chip cookies in the waffle iron – brilliant! I tried it and the recipe was pretty good. The cookies taste like chocolate chip cookies, but because of the waffle shape, they are crispy on the outside and chewy on the inside. Also, they were a hit when I served them because of their cool and unusual shape. When I mentioned this recipe idea to someone, she said that you can actually make a bunch of things in the waffle iron – she makes “spaghetti waffles” with day-old cold spaghetti mixed with savory batter and herbs and baked into a waffle-patty. Anyone else have ideas, and specific recipes to share? Thanks!
