My kids love egg in a hole for some odd reason. Take a slice of bread, use the bottom of a coke can to cut a hole in the middle. Butter both sides, put it in a pan and crack an egg in the middle. They aren't that good in my opinion, but they are a special camping thing that they go crazy over.
Give this a whirl.
Cut up a few different veggies like onions, peppers or what you like and pile them in middle of skillet. Cut all but about 3/4" of bread out leaving the crust. Lay it over the veggies so they are in the middle. Crack an egg of two in the middle and cook it up like an omelette. Take another piece of bread, leave whole and butter one side. Lay it on top with butter side up and then flip the whole thing over. Cook that for a minute or two and you have an omelette sandwich. 
Do you wait for egg to cook then put bread on top and flip immediately ?
Yep that's what I do. I don't leave much bread on the bottom piece so that the egg has plenty of room to spread out and cook
