When I was in college at FSU there was a great place called Bagel Bagel. The had an awesome sandwich called a Wine & Cheese. Here is a recipe for the dressing/sauce that I found and tweaked.
1/2 cup dry white wine...doesnt have to be expensive
1 cup mayo
1/3 cup grated parm cheese
3 tablespoons honey
2 teaspoons dijon mustard
1/2 teaspoon ground black pepper
1. Simmer wine over med-high heat for 2 to 3 minutes.( Reduced to 1/4 cup)
3. Whisk mayo, parm cheese, wine reduction, honey, and pepper til smooth.
You can add to a bagel sandwich or at as a salad dressing.
