To prepare dressing, whirl lime juice, ginger, soy sauce, shallots, jalapeño pepper and salt in a food processor for 20 – 30 seconds. With motor running, gradually add olive oil in a thin stream. Pour into a small saucepan, and heat gently on the sideburner just until bubbling.
Reduce barbecue temperature to MEDIUM, and lightly brush cooking grids with vegetable oil to prevent sticking. Place beef on the grids and grill for 2 minutes, quarter turn for 2 minutes, turn over for 2 minutes, and a final quarter turn for 2 minutes to give beautiful looking grid marks to your beef!
