Southwest Cheesy-Beefy Pasta

This dish is super quick to put together and so yummy!  It's very filling and delicious, with the perfect little kick.  Enjoy!
-1 lb extra lean or lean ground beef (if using fattier beef, drain excess grease after browning)
-1 (1.25 oz) packet taco seasoning
-1 (10 oz) can diced tomatoes with green chilies (do NOT drain)
-1 (15 oz) can sweet corn, drained
-2 cups dry pasta (I like using elbow macaroni)
-3 cups water
-4 oz cheddar cheese, shredded
-1 small tomato, chopped, for topping
-sour cream, for topping
In a large skillet/pot or even wok, brown the ground beef, breaking it as it cooks. Sprinkle the taco seasoning and give it a good stir.  Add the tomatoes with chilies, corn, pasta and water.  Mix well and bring to a boil.  Cover, reduce heat, and simmer for 10-12 minutes.
Uncover and remove from heat.  Top immediately with the shredded cheese.
Serve with a dollop of sour cream and fresh chopped tomato.  Enjoy!
