Martha's Vineyard Salad with Raspberry-Maple Dressing

Source: This is one of Chyrel's recipes and it is really good.

Dressing
1/2 cup raspberry vinegar
1/2 cup olive oil
1/2 cup vegetable oil (Chyrel uses canola)
2 tablespoons Dijon mustard
2 tablespoons tarragon leaves (dried)
1/2 cup PURE MAPLE SYRUP, do not use imitation
Salt to taste

Whisk dressing ingredients together to blend.

Martha's Vineyard Salad
2 cups washed and dried Bibb lettuce
2 cups washed and dried red lettuce
2 tablespoons blue cheese
6 red onion rings, 1/4-inch slice
4 teaspoons coarse chopped toasted walnuts

Put lettuce in a nonreactive bowl, drizzle with dressing until lettuce is thinly coated. Divide up between 2 salad plates, top each salad with onion rings, 1/2 of the blue cheese and 1/2 of the walnuts.

To toast walnuts, break up coarsely, heat oven to 350 degrees F for about 6 minutes, just to toast lightly.

Serves 2.
