Bring 6 cups of water to a boil in a large pot.
Add macaroni pasta and cook for 7 to 9 minutes or until al dente.
Drain the pasta thoroughly and return it to the pot over low heat.
Add the cheese powder packets, evaporated milk, butter, and taco seasoning to the pasta.
Stir the mixture continuously until the butter is melted and the sauce is uniform in texture.
Fold in the drained canned protein and the undrained diced tomatoes with green chilies.
Continue to stir over low heat for 3 minutes until the protein is thoroughly heated and the sauce has thickened.
Remove from heat and allow to rest for 2 minutes to set the sauce consistency before serving.
