We only like gluten free bread if it is cooked like a grilled cheese, toasted or waffle-ironed. Our toaster belongs to the gluten eaters in the house, so we often use a small frying pan and a little bit of butter to cook our sandwiches. You could use whatever you feel comfortable using, even a sprayed olive oil works just fine. This, I believe, is a photo of one of my daughter's creations, which I think is a grilled peanut butter sandwich. Other combinations are grilled PB&J, grilled peanut butter and Nutella, grilled cheese (of course), grilled ham and cheese, grilled BLT and grilled bacon and egg sandwiches.
We are gluten free, but we aren't suffering, that's for sure.
