Those look awesome. I tried this once, very similar recipe (my mother's of course, grew up eating sloppy joes) and I put it in the smoker for a bit, low temps. Your's looks way better than mine, but I did mine in a loaf pan and I thinked I dried the beef out a little. Regardless, I would of had three of those, hahaha.
