Gourmet Steak And Cheese Sandwich

Whisk together the first 7 ingredients. Then gradually whisk in the olive oil. Place the steak in a shallow dish and pour all but 2 Tbs. of the vinaigrette over the top. Marinate for at least 1 hour in the refrigerator.

In a blender or food processor, puree the cheese, cream cheese and lemon juice. Transfer to a bowl and add the walnuts.

In a large skillet, heat the olive oil over medium-high heat. Add the steak and saute, turning once, for 7-8 minutes per side (adjust time for desired doneness).

Slice into thin strips. Toss strips with remaining vinaigrette. Spread cheese mixture evenly on both sides of each Kaiser roll and fill with the steak strips. Add lettuce. Serve.
