So thanks to everyone here for the wonderful ideas! I was in a rut and wanted to use my Masterbuilt XL today, but after I read some posts here about meatloaf I decided to give it a try!
I picked up about 4 lbs of lean hamburger, 3 lbs of ground pork, tossed in a few chopped onions, some homegrown fire-roasted red peppers, 5 duck eggs (we raise ducks) and some breadcrumbs and spices, and POOF! Epic meatloaf. Toss on a bacon weave and introduced it to my smoker for about 4 hours. I smoked it using mesquite and plum wood until the internal temp was about 170+.
One thing I thought of beforehand was putting in a large disposable roaster pan for my water pan. This was big enough to catch the drippings and LOTS of grease. Plus for .99 cents I can toss in when I'm done.
Thanks again to everyone for the ideas! Enjoy the pics!
