Mexican Casserole

This casserole is very hearty and delicious. I didn't know what to expect while making it, but I was very pleasantly surprised at how scrumptious it turned out. The best part is that it's easy and satisfies that mexican food craving. I'm a big fan of mexican food so this hit the spot perfectly.

1 pound ground beef
1 onion, chopped
1 stalk celery, chopped
1 Green Bell Pepper, chopped
8 ounces egg noodles
1 (15 ounce) can chili
1 (14.5 ounce) can peeled and diced tomatoes
1 (15 ounce) can whole kernel corn, drained
1/4 cup salsa
1 (1 ounce) package taco seasoning mix

In a large skillet over medium heat, combine the ground beef, onion, pepper, and celery and saute for 10 minutes, or until the meat is browned and the onion is tender. Drain the fat and set aside. In a separate saucepan, cook noodles according to package directions. When cooked, drain the water and stir in the meat mixture, chili, tomatoes, corn, taco sauce and taco seasoning mix. Mix well and place entire mixture into a 10x15 baking dish. Top with shredded cheese.
