Those are probably great.
have not done these in a long time. Never put pepperoni on them when I did, but good idea.
If you have good American not the Kraft plastic stuff. You can quarter it and make nice little crackers from it.
Something else that is good, and works great in a cast iron skillet, is a thick 3/8 to 1/2 slice of cheese. I have tried many different ones. get you skillet hot lay the slice in and it will brown and start to melt cook some of the oil out of it, when it gets to your liking on how brown flip it over, and do the other side until you like it. then take it out salt and pepper. crisp in the outside warm and soft inside. Some cheese is messier than others. Now you have oil for your eggs.
