I tried this a few weeks ago with mild success and no photos so it never happened right? :-) This time I used a pound of ground beef with a little added water to help it stay moist. I also added 1/4 of an onion diced and 3 slices of bacon diced, with some worcestershire sauce and some rub. Once I got the meat flattened I put a few slices of American cheese and some shredded cheddar. Threw it on the grill with some turkey breasts I brined. They both came out good. I used some Western Hickory BBQ mini logs for the smoke this time. Everything turned out great. Finally had a fire going good that gave it great hickory flavor without the charcoal flavor and the turkeys came out moist and tasty. The last time I tried this my fattie came out dry, but my temps also got way too hot. This time it was much better. The beef really masks the bacon flavor. I think next time I will add some strips of bacon to the hamburger roll to make sure and get that good bacon flavor. The turkey came out great with nice flavor and moist. Too bad next thanksgiving is 11 months away. I guess I can keep practicing and be a pro by next year!
