1 lb ground beef
2 cloves garlic, minced
½ onion, diced
1 celery stalk, diced
1 cup mushrooms, diced
1 lb penne
2 cups salsa
1 cup sour cream
1 packet taco seasoning
½ cup frozen corn
1 can black beans or kidney beans, drained and rinsed
1 cup cheddar cheese, shredded
Preheat oven to 350 degrees. Put on a big pot of salted water to boil for the pasta.
In a frying pan over medium-high heat, fry the ground beef with onions, celery, mushrooms and garlic. Once browned, add the taco seasoning.
Add the pasta to the boiling water and cook until al dente (you want the pasta to be just slightly underdone because it will continue to cook in the oven.) Drain pasta.
In a large casserole dish, stir together beef mixture, pasta, corn, beans, salsa and sour cream. Once all combined, sprinkle shredded cheese over the top. Place in oven for 25-30 minutes until the cheese is nice and melted and the dish is heated through.
