Southwest Mac and Cheese

Sometimes when you're just learning to cook it is easy to take prepackaged meals and add things to them.
This is my "Adult" mac and Cheese dinner.

1 package of macaroni and cheese. Kraft is the best.
1 lb of ground beef
1 can of diced tomatoes
1/2 diced onion
1 clove a garlic
1 small package of frozen veggies-something with a southwest theme
salt
pepper
taco seasoning
milk
butter
vegetable oil

Get everything out of the pantry and refrigerator before you start. Carefully dice the onion and garlic. Set them aside. Put about 1 quart of water in a large pot and start it to boil.
In a large skillet and the oil, and heat it slowly. Add the onion and garlic. keep stirring them occasionally. don't let them stick to the bottom or burn.
When the water is boiling add about 1 T. of salt and the macaroni. set the cheese pack aside. stir the pot so the macaroni don't stick together. turn down the heat to low and cover the pan.
add the ground beef to the onions. break it up while browning. add some salt, pepper and taco seasoning. I always add to taste. add the veggies. and continue to stir and break up the meat.
when it is brown add the tomatoes. turn down to low simmer and cover.
drain the water from the macaroni. set the macaroni aside. in the sauce pan, on low heat melt the butter that the mac and cheese package requires. slowly add the milk. When the it is melted and well Incorporated add the cheese pack. stir it around break up any lumps.
add the macaroni to the pot and fold slowly.Let the macaroni heat back up. Add the meat and veggie mixture to the pot and fold in slowly.
That's it. Make sure you have enough seasoning. and serve.
Refrigerate any leftovers after it has cooled.
