Beef Teriyaki

I believe that this recipe was my Grandma's. My mom has always made it and it is one of very few Asian dishes that my family prepares.

1 beef roast or stew meat pack that equal the size of a roast
½ bottle soy sauce
1 tsp ginger
1tbsp brown sugar
salt and pepper to taste
meat tenderizer as desired
2 tbsp water
1 tbsp cooking oil

If you buy roast, cut the meat into squares. If you buy stew meat then you can skip this step. Combine the above-mentioned ingredients and pour over the meat. Marinate for atleast five hours and bake at 350 degrees until it cooked all the way through.
