I guess I'll call it...

Chili Mac. This is what I made for lunch on Wednesday. It is super yummy, and quick! This recipe makes a full 9x13 pan.
Gather your in ingredients.
1 lb. ground beef
1 medium onion
1 can diced tomatoes (drain some of the juice out.)
1 large can spaghetti sauce
2 lbs. macaroni
about 2 cups shredded cheese
spices of your choice

Boil water in a pot for the macaroni. Heat a skillet to cook the ground beef and onion in. Pour a tablespoon or so of olive oil in the skillet.

Chop the onion.

Add onion to skillet and saute until transparent. Add ground beef and cook thoroughly. Once meat is cooked, you may add whatever spices you like. I put in garlic powder, a bit of taco seasoning, and cumin.

Boil pasta, and drain.

Pour the sauce, tomatoes, meat, and pasta in the pot.

Stir until combined.

Pour into a lightly greased 9x13 pan, and sprinkle cheese over the top, if desired. Bake in a 350 degree oven for about 15 minutes, or until the cheese is melted and the pasta is heated through.
