John's Pot Roast & Gravy

Ingredients:
Beef (I usually use about 3 pounds)
2 cans French Onion Soup
Chopped carrots (About 5 carrots)
Chopped potatoes (about 3 potatoes)
Chopped mushroom (adjust to your preference)
2 onions cut in wedges
2 bay leaves
thyme (about 1 teaspoon)
black pepper
flour

Add all ingredients except flour to a large pot (or Crockpot). Allow mixture to cook at a medium to low for 4 - 6 hours. After cooking remove bay leaves and serve. To make the gravy, remove some of the stock from the pot and add it to a large pan. While simmering, slowly and evenly add flour while stirring. Serve with or without white rice.
