I'm eating a leftover popover split on the equator and toasted in the oven at 375 F for about 7 minutes until dry and crispy again. I took it out, topped with slices of medium cheddar, a little oregano and crushed red pepper. Edited: I put it back in the oven for a couple or three minutes to melt the cheese.
Seriously good. Not ghetto pizza. More like uptown toasties. I did buy some English muffins on the last grocery haul, though, so those are in the future too. I always called them ghetto pizza, but I like the eG moniker of toasties. It just sounds classier.
