Hello again Linda!
While I don’t have a macaroni and cheese recipe that specifically includes artichokes, I think that sounds wonderful!  There’s no reason you couldn’t add some artichokes to my Traditional Macaroni and Cheese recipe, or to my Two-Cheese Macaroni recipe.  You can use either fresh steamed artichoke hearts, frozen, thawed artichoke hearts or canned artichoke hearts (make sure in any case that you pat them dry first, otherwise they can thin out the cheese sauce).  Fold them into the cheese sauce with the macaroni and bake as directed for a gourmet take on a classic comfort food.  I do hope you try it and let me know how it turns out!
