Arugula Salad

2 tbs balsamic vinegar
1 tsp Dijon mustard
1 clove garlic
1/2 cup olive oil
2 cups salad mix
1 cup arugula
1/2 lb. mushroom, sliced
1 sweet red pepper, cut into thin strips

In a small bowl whisk together vinegar, mustard, and garlic. Add oil in a slow, steady stream, whisking until well blended. Let mixture stand in bowl for 5 to 10 minutes to allow flavors to meld. Wash salad mix and arrange on four salad plates. Distribute arugula among plates. Arrange sliced mushrooms and peppers on top. Drizzle salad dressing over each salad just before serving.
