Here's a link for a bunch of different cobblers that look very close to what I have used:

For an easy breakfast, put 2-3 eggs (without shell!!) in a Freezer Ziplock per person. Bring a large pot of water to a boil and have everyone take one of the bags, write their name on it with a sharpie then add whatever additional ingredients they want into the bag. ie grated cheese, onion, bell pepper, sliced Canadian bacon, bacon bits, cooked sausage, etc. Drop the bags into the boiling water and cook til done. Very simple and all of the "fixins" can be prepared in advance. No cleanup and everybody gets their own custom "Omlet"!! Try it at home first.
If you are a hand with a Dutch Oven, prepare about 10-12 charcoal briquets placing the oven on top of half and put the other half on the lid. With 3-4 Ball canning lid rings in the bottom of the oven, place a pie pan filled with canned biscuits (after the oven has heated up) and bake until done. Without the lid rings, you'll burn the bottom odf them every time!!
For a large group, you will need to stage some more charcoal to replenish the oven with.
Take care.
