I love this recipe! Tangy and sweet, it's great on spinach with fresh mozzarella cheese, mandarin oranges or fresh strawberry slices, slivered almonds, bacon bits and red onion slivers.
1/2 cup red wine vinegar
1 cup sugar
1/2 tsp salt and pepper
1/2 red onion
2 tsp mustard
1 cup olive oil
Mix all ingredients except oil in a blender.
Add oil and blend until smooth.
