Preheat oven to 350°.

Place roast into 9×13″ baking dish. Spread onions under, around, and on top. Put potatoes around sides (if desired).

Mix together A1 sauce, teriyaki, and garlic salt. Pour over veggies and meat. Next, add in enough water so there is about 1/2 inch or so of liquid in the pan.

Cover with foil and bake for about 90 minutes to 2 hours until the meat is falling apart. Normal folks would probably cook it for about an hour or until the meat is fork tender.

To make gravy, mix together 3 tablespoons of corn starch and 1 cup or so of water in a small sauce pan. Stir in drippings, and bring this to a boil; remove from heat. If it tastes bland, add in a cube of beef (or chicken) bouillon, A1 sauce, garlic, salt, and/or pepper.
