Here is a loaf I Q'd a few months back...looking to do it again pretty soon,
2lb hamburger
1lb Jimmy Dean hot
1 red pepper (large)
1 purple onion (a big one I cooked it a little to soften it)
4 slices sourdough bread ripped up and tossed in a bowl.
milk poured over them until they stop soaking it up.
About 2 tables spoons of my pork rub and 2 table spoons of D-Dogs apple rub
A squirt of ketchup
3 Eggs
Garlic (about 2 cloves)
Mix for awhile to make sure you have no big chunks of bread or anything
I formed them up and cooked them on the drum at about 250. When the internal temp reached about 150 I poured on the glaze and kicked the heat up to about 300 took them off at 165 and they sat for 30min before we ate them.
I did sit them on foil for the first little while, I was afraid they would fall apart on the grates.
