I used more dijon (about a tbsp more), white wine vinegar (didn't have any red) and fresh garlic instead of powder. Also, I added a couple of diced mission figs for a touch of sweetness. I used rotini pasta instead of penne. I'm not entirely sure whether this is supposed to be served hot or cold...i served it room temp. I used probably about 4 tbsp of mayo and a 1/2 cup of Parm. This dish was okay. Nice to try but no one is clamoring for more. I can see taking it to a BBQ...but I'd probably come home with some.
