Coming up with a title for this one was a bit tricky. I was torn between Green Chile Cheesy Mac and Green Chile Beefy Mac...but I suppose it really doesn't matter because, in the end, it's the Green Chile that gives it this recipe so much flavor. I love it because it is so delicious, and because you can make it all in one pot, without dirtying too many dishes.
Heat large pot on stove top with enough olive oil to coat bottom of pan. Add in ground beef and cook. (Drain any liquid/fat that is rendered) Add in chopped onions and sauteé. Add in minced garlic, chopped green chile, salt and pepper. Mix to combine and let cook a couple of minutes before adding in tomato sauce, 1 cup of chicken broth, and milk. Stir and let it come to a boil. Add in pasta. There should be enough liquid to just barely cover pasta, if not, add in more chicken broth. Simmer for 7 to 10 minutes, until pasta is fully cooked. Add in shredded cheese and mix until fully melted. Remove from stove and serve while hot.
