In 2-gallon soup pot, saute onions, carrots and celery in margarine over medium heat until tender. Add garlic, pepper and seasoning salt, stirring well. Add 1 gallon water, bouillon cubes, potatoes, tomatoes, cabbage and corned beef. Add additional water to cover vegetables and nearly fill pot if needed. Bring to boil cook 30-45 minutes, or until potatoes and cabbage are tender. Add rice and cook until done, about 2 minutes. Makes about 10 servings.
