I've been making this for years. I usually just "chop and dump", so I've gotten the proportions as close as I can, I think. Add more or less mayo, if you like, because I usually don't measure. The same with the tarragon and dill weed. Add more if you like it, less if you don't.
Elegant but hearty chicken and wine dish. A nice blend of Burgundy, herbs, and garlic. I serve this with hot cooked noodles, crusty French bread, and a salad for a wonderful company meal. And don't forget the wine!
