Skillet Taco Mac Hotdish

8 ounces of macaroni, cooked
1 lb. ground beef
1 chopped onion
1 can black beans
1 14.5 ounce can diced tomatoes
1 can corn
1 cup salsa
1 pkg taco seasoning mix
1 1/2 cups shredded cheese
1/2 c sour cream

• Prepare pasta according to package directions.
• Meanwhile, in large skillet, cook ground beef and onion
• stir in black beans, tomatoes, corn, salsa and taco seasoning.  Bring to a boil; reduce heat and simmer 5 minutes
• Stir in 1 cup cheese, sour cream and pasta. Top with remaining cheese, serve.

NOTES: 

• I cooked everything in one pot after the macaroni was done.
• I didn't have taco seasoning, so just added a little cumin and chili powder.  Really, the salsa covered it pretty well anyway.
