Mix up the Worcestershire sauce, lemon juice, soy sauce and a bit of pepper. Mix in the meat, flour, celery, mushrooms, and onion. Heat the oil in a pot with a lid. Dump the meat and vegetable mix in and cook over medium high heat for 5-10 minutes, letting the meat brown a bit and stirring periodically.
Add the water and bring to a boil. Lower the heat, cover, and simmer 1 to 1-1/2 hours. Add the green pepper strips and cook another 5-10 minutes, covered. Stir in the cherry tomatoes (or slices of larger tomatoes if that's what you have, or even a can of diced tomatoes!) and cook another 5 minutes.
