Grilled Cheese?

I'm sure this will be more for fun, I'm not sure how controversial this gets here, but for the sake of settling a controversial argument between my husband and I. Grilled cheese sandwiches...are they considered a breakfast food or more like a lunch/dinner type food?

Yes, they can be eaten at anytime, I was going to include that as an option in the poll, but I'm more interested in what you ladies/gentlemen have to say in terms of whether you think it's considered breakfast food or more so something you'd cook for lunch/dinner.
