Hey goat, I have a great way to make omelets for 10-15 people at once and ya only use a big spagetti pot.
Pre cook lots of stuff for interior; sausage, bacon, onion, mushrooms, green peppers.
Beat a bunch of eggs with salt and pepper added.
lay out all the stuff in bowels and lay out magic marker and plastic zip lock bags.
Each person puts whatever they like in a plastic bag which they write their name on and then adds a 1/2 cup of egg to the bag. Zip it up.
When they are all ready, dump in in boiling water in the big pot (can use a outdoor crab cooker) and after 10 min, read the names out and each person dumps em on a paper plate.
It sounds crazy but works really well.
