Totally agree with you. I will never made another meatloaf again without putting in the smoker. I have made meatloaf twice in all the years of cooking for my boys but since we smoked our first, they have asked a half dozen times for more. I brought some in for my co-workers (ie: my food test panel....lol) and one "non-believer" said she didn't like meatloaf at all but tried it anyway. She came back for a second piece. No bigger compliment than that.
And next time? Try making some meatballs for sauce also. Gives your sauce a WHOLE different flavor profile.
