Taco Bake

We found this in our Dollar General believe it or not... decided to give it a try and we LOVE it. Easy, the kids will like it and it's cheap too! You can also find more recipes from Kraft here.
Kraft Taco Bake
1 pkg (14 oz) Kraft (or any really) Macaroni and Cheese Dinner
1 lb ground beef
1/8 cup chopped onions
1 pkg taco seasoning
3/4 cup sour cream
1 1/2 cups shredded cheddar cheese, divided
1 cup of chunky salsa
Heat the oven to 400F. Prepare the mac and cheese dinner as directed on package. While that is cooking, saute your onions in a LITTLE bit of butter or oil. When translucent, add meat and cook until no more pink shows. Drain out the fat and move back to heat and add taco seasoning until mixed in well, remove from heat. Stir the sour cream in to the mac & cheese, spoon 1/2 of this mixture in to a 8 in square baking dish. Top with a layer of the meat, then 1 cup of the cheese, and finally the rest of the mac; cover with foil. Bake for 15 minutes, take out and top with salsa (or not if you're like my husband) and then cheese on top of that. Bake for an additional 5 minutes or until cheese is melted. Enjoy! It's really quite easy!
