" Heat grill to medium-high. In a medium bowl, toss the tomatoes with 1 Tbsp of the oil and 1/4 tsp each salt and pepper. Season the steak with 1/2 tsp salt and 1/4 tsp pepper and grill to desired doneness, 4 to 5 minutes per side for medium-rare. Let rest at least 5 minutes before slicing. Meanwhile, brush both sides of the onion slices with the remaining 2 Tbsp oil and sprinkle with the blackening spice mix. Grill until blackened and tender, 5 to 6 minutes per side. Grill the tomatoes just until charred, 3 to 5 minutes per side. Form sandwiches with the bread, lettuce, steak, onions and tomatoes."^^<http://www.w3.org/2001/XMLSchema#string>
