Barbecued Hamburgers

There's nothing like barbecued burgers in the summer! Sometimes I just pat the meat into patties but I like to add a few things for flavor. In general, I mix the meat up, pat into burgers about 1/2 inch thick.

Tonight we did:

1 pound burger
3 Tbs or so of barbecue sauce
3 Tbs or so of grated Parmesan cheese

My usual mixture is:

1 pound ground beef, 80 or 85 percent lean
1 egg
1/2 to 3/4 cup breadcrumbs
1 Tbs horseradish
1 Tbs or ketchup
1 tsp or so mustard

I noticed these burgers did not hold together as well, with a few splitting open on the grill. I think the egg and bread crumb mix holds them together better, just like a meatloaf. But the barbecue sauce and Parmesan tasted good. Next time I might mix it with the egg and bread crumbs as well.

I remember trying a recipe once that had red wine in with the hamburger and another that had some Cajun seasonings. Anyone got a favorite hamburger mix to share?
