1. Slice the grilled beef
across the grain into bite-sized pieces about
2 1/2 inches long and 1/8 inch thick.
2. For the dressing: In
a medium bowl, stir together the fish sauce,
stock, lime juice, chilies and sugar. Taste
the dressing with some of the beef and adjust
it to your liking with additional fish sauce,
lime juice, sugar or chilies. Pour the dressing
over the beef, cilantro and green onions.
3.
To serve: Arrange five large lettuce leaves around
the rim of a large serving platter. Cut the remaining
lettuce into a coarse chiffonade and mound it
in the center. Mix the cucumbers, tomatoes, rice
powder and half the mint leaves with the beef
and place it on top of the chiffonade with a slotted
spoon. Moisten the salad with any extra dressing
and then garnish with Crispy Shallots and the
remaining mint leaves. Serve immediately.
