See Gina's version here.
I lurv cheese, especially in partnership with mac, and I like that Gina put some veg into her recipe to round it out as a meal.
I, in typical Angie fashion, immediately started making my own substitutions to the recipe. I.e., I used some soy milk, margarine, and frozen broccoli instead of fresh. Mostly because that was what I had on hand and in my opinion that was close enough.
I should also confess that I used about twice the cheese as the recipe said, thus probably nullifying the "skinny" part of the recipe.
Saute up some onions in some buttah. And margarine. Buttah for flavah, margarine to round it out and avoid some calories. Although it was all for naught in the end. Also get your pasta cooking so it's ready to combine later.
Good for leftovers too!!
