I have completely replaced mayo in some cases with greek yogurt but usually by creating some flavored sauce from the yogurt and herbs. I grilled a couple turkey breasts tonight and I am planning to cube them tomorrow and make a "turkey salad" for sandwiches. In trying to eat more healthy I don't think I could completely replace mayo, but has anyone cut mayo with greek yogurt to reduce the fat? I happen to love the tang. Should I go 1/2 and 1/2?
