Season ground beef with garlic powder, onion powder, Cajun, and half taco seasoning packet. You can use a full packet of taco seasoning but just add to taste. Everyone's taste buds are different. Then cook until slightly browned or done.
Cook the box of Mac' n cheese according to instructions on the back of the box. I put my noodles in after the water has started boiling and let them boil for 10minutes, then I add in the butter, packet of cheese the Mac comes with, milk, and add an extra 2 slices of cheese. Let it cook, stirring frequently so it doesn't stick, until all the cheese and butter is melted and mixed together
Combine the Mac' n cheese and the seasoned ground beef together. Mix together well and serve.
