Greek Yogurt Alfredo Sauce-previous pinner said: This was AMAZING!! I couldn't believe it's the healthy version. I made a few changes to the recipe. I used 3 tablespoons of minced garlic, added a few dashes of Cayenne Pepper and I used 1/2 cup of grated Parmesan in the sauce. I also added a bit more greek yogurt and chicken stock because I put chicken breasts in the pasta too. I will definitely make this again!!
