I love that it is a one pan meal, makes clean up and prep much easier. This would make a great meal in a bag.
Pick a 3 qt pan, any shape with a lid. Whisk the gravy mix, sour cream powder and spices into half the water. Add the mushrooms, with liquid (about 1/4 c. per can) the beef with any broth, the macaroni and the last 1 1/2 c. water. Put the lid on and simmer until the pasta is cooked, about 15-20 minutes.
I added about 2 tsp of Worcestershire Sauce since this is something we keep in our food storage. I will serve the meal with the bottle (Makes me sound like a lush, eh?) on the table for those who are bigger fans of it than I.
