Directions

  1. To make marinade for lamb in a food processor chop rosemary, basil and garlic together to form a paste. Pour oil through food tube. Spread marinade over lamb and then sprinkle with salt and pepper. Cover and refrigerate 6-8 hours (or overnight).
  2. To make mayonnaise: In a food processor combine basil, yolks and lemon juice and process until smooth (1 minute) and then slowly add oil through food tube. Season with salt and pepper. Transfer to a bowl and add nuts. Refrigerate until serving (can be made one day ahead).
  3. To make mustard: In a medium bowl or jar whisk together oil, mustard, rosemary, vinegar and white pepper until thick. Refrigerate until serving (can be prepared one day ahead), but serve at room temperature.
  4. Prepare barbeque with wood chunks. Cover and heat to 160-degrees F. Place lamb on rack, cover and smoke for 45-60 minutes, covered or until meat therometer reads 140-degrees F for medium rare. Remove lamb from gril and let rest 15 minutes before slicing.
  5. To make sandwiches: brush both sides of bread slices with oil and sprinkle with salt and pepper. Grill until golden brown on both sides. Transfer to platter. Spread one side of each slice of bread with mayonnaise and top with watercress. Cut lamb across the grain into thin slices and place on top of watercress. Drizzle each sandwich with mustard. Serve.
