Grilled Lamb, Potato, Bean and Mushroom Salad

The lemony Dijon mustard dressing is used both to marinate the lamb and to coat the salad. And don't let the anchovies in the dressing scare you off. They add depth of flavor, but not a fishy taste.

Recipe Ingredients:

3/4 cup Dijon mustard
1/2 cup fresh lemon juice
3 (2-ounce) cans anchovies, drained, oil reserved, anchovies chopped
1 1/3 cups oil
1 1/2 cups chopped fresh basil, packed
