Sloppy Joe Spaghetti Bake

1 lb ground beef

1/2 onion, diced

1 15oz can diced tomatoes

1/3 cup ketchup

1 1/2 tbsp mustard

1 tbsp brown sugar

1 tsp chili powder

1/2 tsp cumin

1/4 tsp black pepper

1/2 lb spaghetti, cooked and drained

1 cup shredded cheddar cheese

1.  Brown ground beef with onions in a large skillet.  Drain.  Stir in tomatoes, ketchup, mustard, brown sugar, and seasonings.  Simmer for about 10 minutes, until flavors are combined.  Remove from heat.

2.  Place cooked spaghetti noodles in a casserole dish and top with sloppy joe mixture.  Cover with cheddar cheese.  Bake at 350 degrees for 10 minutes, or until cheese is melted.  (Or, refrigerate until dinner time and then bake for about 20 minutes, until heated through.)
