All good stuff. I do whole pieces of backstrap, like BAO does. I marinate the piece (8" or so for four people) in Teryiyaki "quick marinade", with a dash of basil, chili powder, parsley, and enough olive oil to coat. Let it sit an hour or so. Sprinkle McCormick's Montreal Steak Seasoning liberally over it, then grill over hot coals until still pink inside, remove & cover in foil & set aside. Slice in about 10 minutes, after you have your salad or whatever.
Slice and serve with sliced red bell peppers you've sauted quickly in hot olive oil (w. salt & pepper on the peppers) until tender & bubbling. Put peppers over the top of the platter of backstrap. Goes good with any good red wine, by the way.
Yum. I do venison about twenty different ways, but the only thing beating this is venison tenderloin!
