Beef & Mac Throw Down

I, for whatever reason, have not made this a house tradition.  I have no clue what reason that could be or is...but it is in the process of being remedied.  To be honest, we used organic BISON in our last throw down...

1 pkg (16oz) noodles...typically elbows, but we used shells, wagon wheel, etc & kids loved any
1 lb browned beef (or Bison...I would imagine you could also use ground turkey, or bite size pieces of turkey or chicken, anything really should work great in this "setting")
1 onion, diced
2 jars favorite spaghetti sauce (we like the spicy kind w/garlic & "goodies"  Don't do the onion above if your sauce already has chunks of onion & such in it)

Cook & drain noodles of choice (remember, after draining rinse in COLD water to stop cooking)
In a large skillet, add all ingredients (saute your onion first if you are adding it & its not part of the sauce), heat through.  Serve w/some cheese sprinkled on top.

Yup...its that easy...again I wonder WHY this is not a staple in the house...
