Nothing says comfort food like grilled cheese. To get the maximum amount of comfort-food-goodness, you need the real thing - real butter, real cheese, and good bread.
This sandwich used about two ounces of the gluten free bread I buy at my farmer's market, a solid ounce of cheese, and half a tablespoon of butter. I don't bother trying to smear the butter on the bread anymore. It's a waste of time and I always end up with bread that's falling to pieces.
