1 can (14-1/2-oz.) diced tomatoes

1 cup shredded sharp cheddar cheese
chopped green onions, for garnishment (optional)

Directions:  Cook pasta according to package directions.  Meanwhile, in a large skillet, brown beef and onion over medium heat until meat is no longer pink; drain.  Stir in the tomatoes, mustard, ketchup, relish, steak seasoning, and seasoned salt.  Bring to a boil.  Reduce heat; simmer, uncovered , for 5 minutes.  Stir in drained pasta.  Cook for 1 minute more.  Sprinkle with cheese.  Remove from heat; cover and let stand until cheese is melted.   Garnish with green onions if desired.  Enjoy!
