1/2 cup raspberry or balsamic vinegar
1/4 cup seedless raspberry jam

3 quarts (about 8 oz.) salad mix, rinsed and crisped
1 1/4 cups raspberries
4 ounces log-shaped fresh goat cheese, cut into 8 equal slices
Whisk together raspberry vinegar, jam, lemon peel, and sugar until jam is completely dissolved and smooth. Reserve half the mixture. Pour remaining mixture into a bowl.
