Melt butter in Dutch oven. Cut Frankfurters in half lengthwise; then cut each half into 3 pieces. Saute frankfurters, onion, and green pepper in butter for about 10 minutes or until franks are browned.

Sprinkle macaroni over top. Add salt, tomatoes, and water. Cover and bring to a boil. Reduce heat and simmer, stirring occasionally, until macaroni is just tender, about 12 minutes. Stir in cheese and simmer until cheese melts. Serve immediately.
