Preheat grill or barbecue.
Lightly coat meat with oil and season with salt.
Grill meat for 5 to 10 minutes per side (looking for medium-rare).
Transfer to cutting board and let rest for 5 to 10 minutes.
Meanwhile, in a large bowl, combine the lettuce, cucumbers, tomatoes, onions, and herbs.
Refrigerate while preparing dressing and allowing for meat to cool.
In a jar with lid, place together the lime juice, fish sauce, garlic, jalapeños, sugar and oil.
Place on lid and shake vigorously.
Dip a piece of lettuce in the dressing and check seasoning; add more jalapeños, if you like.
Once meat is cooled, cut against the grain into very thin slices and add to salad bowl.
Drizzle the salad with just enough of the dressing to lightly coat and gently toss together (excess dressing can be kept for up to 2 weeks in the refrigerator).
