Usually we don't like dips with mayonnaise. I took a change and made this recipe. It was really good. I made half the recipe, used a vidalia onion and a pie plate. It was perfect. Thanks Kit :) Made for I Recommend tag game

This dip was a big hit for Thanksgiving, it was savory and creamy. It kept you wanting more. Even people who did not know what it was at first and do not like onions ate it. It was delish!
