1 chuck arm roast (trimmed well)
1/4 c. soy sauce
1 tsp. - 1 tbsp. chili powder (depending on your taste)
Salt & pepper to taste
1 1/2 c. boiling water
2 tsp. cornstarch

Combine all ingredients and pour over roast and bake 350 degrees until tender. I usually put mine in a crock pot and cook for about 5 hours or until tender.
