Ok this is a no brainer!
A Waffle Iron
That's it....... you can figure out the rest.
What a brilliant idea to make for kids that love grilled cheese ...... adults that love grilled cheese...... ok, everyone that loves grilled cheese.
Make them plain or make them fancy, you all know what you would add to a grilled cheese sandwich made in a waffle iron. I know I have a few ideas!
Peace in the Kitchen!
