On our way through Hatch, N.M., in 2015, I bought some some mild-green-chili powder for myself and Jeannine Dahl, my dear mother in law and cooking partner. We’ve shared many good times in her Arizona kitchen, trading ideas on how to tweak traditional American classics. This is a mellow Southwestern twist on Mac and Cheddar, with portions reduced to accommodate our four-quart pasta pot (sauce pan) in The Epic Van.
