When Johnny Carrabba and his uncle Damian Mandola opened the first Carrabba's restaurant in 1986, they used a collection of their own traditional family recipes to craft a terrific Italian menu. You'll even find the names of friends and family in several of those dishes including Pollo Rosa Maria, Chicken Bryan, Scampi Damian and Insalata Johnny Rocco. Now you can easily recreate the taste of the delicious dressing that's tossed into the salad that's served before each Carrabba's entree. And you need only six ingredients. For the grated Parmesan cheese, go ahead and use the stuff made by Kraft that comes in the green shaker canisters. And if you don't have any buttermilk, you can substitute regular milk. Since it's so thick, this dressing is best when tossed into your salad before serving it, just like the real thing.
