In a large soup pot, heat olive oil over medium high heat, add stew meat, and cook until browned on all sides, about 3 to 5 minutes. Add leftover potatoes and tomatoes, chicken stock, green beans and corn. Cook until vegetables are done, about 6 to 8 minutes. Taste and adjust seasonings. Serve immediately.
Use any veggies you can get your hands on, frozen corn, green beans and peas are fine. Anything you have hanging around, if they're already cooked, the cooking time is cut back.
