Preheat the oven to 180 degrees.
In a heavy based pan, over a medium to high heat, add some low calorie spray and then brown the stewing steak for 5-10 minutes or until sealed. Add the bacon and onions, and fry for another 2 minutes.
Stir in the carrots, wine, tomato puree, bay leaves, and mushrooms, and transfer to a casserole dish with a lid. Cook for 1 hour.
Remove from the oven, add 150ml of boiling water, and sprinkle over the gravy granules. Stir well. Add the mushrooms.
Return to the oven for half an hour, or until the meat is tender.
Serve and enjoy!
