4. When you move the meat to the cooler side of the grill, brush the onions and potatoes with olive oil, sprinkle with salt and pepper, and place on the hottest part of the grill. Cook until golden brown, about 2 to 3 minutes per side for the potatoes and 5 to 7 minutes per side for the onions. Remove the vegetables from the grill and place them in a large bowl.

5. Add the lettuce to the bowl with the potatoes and onions. Whisk the dressing well and add it to the bowl, using just enough to moisten the ingredients, then toss gently. Place a portion of salad on each plate. Cut the tenderloin into slices about 1-inch thick, lay several on top of each portion of salad, and serve with corn on the cob and thick slices of grilled bread. A fresh fruit crisp makes a good dessert.

LAMB-LOCKED
Americans shy away from eating lamb, consuming just under a pound per person annually. But this shortsightedness has an advantage: When you buck the tide and serve lamb, it seems unusual and therefore celebratory. Our top choice is the loin chop. The lamb equivalent of T-bone, loin chops are the most expensive type of lamb chops and are both extremely tender and have a delicate flavor appreciated even by people who are not that fond of lamb.
