Spray a 9x13 inch baking dish with no stick cooking spray.
Cut the cubed steaks into desired size pieces.
Place flour into a dish or plate. Place each piece of steak in the flour and pat it onto both sides. Season both sides with salt and pepper and set aside onto a plate.
Spray a large skillet with no stick cooking spray. Heat oil in the skillet over medium heat. Preheat oven to 350 degrees F.
Place 2 or 3 pieces of meat in the oil and brown about 2 minutes on each side. Continue with the remaining steaks. Place the steaks into baking dish.
Prepare the gravy....whisk small amount (1/4-1/3 cup) of flour into the oil, whisk constantly, until smooth. The amount of flour will depend on the oil remaining in pan. **Use the flour the steaks were rolled in. Cook about 3 minutes, or until mixture becomes a caramel- colored brown. Add water slowly and whisk until mixture is smooth. Continue to whisk another 3-4 minutes. Add more water if gravy seems too thick. Pour the gravy over the steaks, Cover with aluminum foil and bake for about 2 1/2 hours. Check meat after 2 hours. Meat will be fork tender, do not over bake.
May use packages of gravy mix if not making gravy from scratch.
