3-1/2 lb boneless lean beef roast
1 teaspoon dry mustard
1/2 teaspoon salt
1/2 cup chopped onion
7 1/2 oz can tomato sauce
2 tablespoons vinegar
1/2 teaspoon thyme
1/4 teaspoon freshly ground pepper
Braising first in tomato sauce guarantees tender, flavorful beef.
Trim all fat from roast. Rub dry mustard and salt into the surface of the meat. Place in a lightly greased, oven-proof dish. Top with onion.
Combine tomato sauce, vinegar, thyme and pepper. Pour over roast and cover tightly.
Bake at 325°F for three hours until meat is tender.
