Being born and raised in Wisconsin anything with cheese is good. Jackie and our friend P.J. like cheese stuffed olives. We got tegether for a girls trip last April in Las Vegas and they had them in their cocktail. We had a great time with old friends. All women need a yearly get together. It is great therapy!
