OK, here is a quick and totally awesome one: Tri-tip roast (Lonon Broil will also work, but reduce cooking time by about 5 minutes). Marinnate it in a bit of soy sauce, Worschestershire sauce, water, garlic at least an hour or over night is best. When done marinating, rub a thick layer of montreal Steak seasoning on teh fatty side. Heat grill up to about 500 deg. (if gas, turn middle burner to low after preheated) set Tri-tip over center burnerl (indirect heat) sjut lid and cook 13-15 minutes with out disturbing it. 13 for med rare 15 for med. turn, cook they same time as first side. At last 5 minutes of cooking, open lid. at pull off time, use tongs, put meat on platter and let rest 5 minutes. Carve into 1/2-1" cutlets against the grain.
You will thank me after. go head...enjoy!!
