Crock Pot Roast Beef

Olive Oil
1 Piece Beef(I used Topside)
Salt and Pepper
1 Onion, chopped
2 Sticks Celery, chopped
2 Cloves Garlic, finely chopped
2 teaspoons beef stock (powder)
2 teaspoons dry mustard
2 tblespns Worcester sauce
2 tblspns tomato paste
1 cup red wine
1/2 cup water
Gravy Powder.

Rub meat with oil, salt and pepper and brown in a frypan.
Place onion,celery and garlic in crock pot (slow cooker), and place in browned meat.
Mix remaining ingredients together, except gravy powder, and pour over roast. Cook til done, (a few hours). Strain liquid, and thicken with gravy .

This is soooo tasty, and the meat is so tender too, also great cold, in sandwiches. Did it for the first time the other day, and just had to share it, as I haven't posted a recipe for a while.
