First time trying this and was it delicious. Took about a 22" length of backstrap and seasoned it with salt, pepper, minced garlic and onion. Wrapped it in tin foil and put on the grill for 1 hour at 350*. Sauteed some mushroom and onions.
sliced the backstrap 1/4" thick, put the mushroons and onions over the top and some of the juice held by the foil. Mmmmmmm. Good
