Searching for a Vinaigrette

Heres one to challenge all of you. My husband and I dined at a Winery and Bisto this past weekend. My salad was a bed of mixed greens, maytag blue cheese, julianned red onions and sliced granny smith apples. The dressing was a Sherry Roasted Beet Vinaigrette dressing. It was the best salad I think I have ever had! Now can anyone try to tell me how to make a Sherry Roasted Beet Vinaigrette dressing? I would be forever grateful. :smiley:
Thanks

Thanks KW! That helps alot! I am going to roast my beets with some olive oil and cooking sherry and salt and pepper. Then I thought I would put it through my food processer with some olive oil and see what happens, you know, play with it a bit. Thanks again! :smiley:
