1. MAKE THE NUOC CHAM DRESSING Combine all of the ingredients
in a medium bowl and let stand for 15 minutes.
2. MEANWHILE, MAKE THE SALAD Rub the steak all over with the oil
and season with salt and pepper. Heat a small cast-iron skillet
until very hot. Add the steak and cook over moderately high heat
for 2 minutes, until browned and crusty. Add the butter, garlic and
thyme to the skillet and spoon the melted butter over the steak.
Flip the steak and cook for 2 minutes longer, spooning the butter
on top. Add the Maggi seasoning, cover and let stand off the
heat for 2 minutes. Transfer the steak to a paper towel–lined work
surface, cover loosely with foil and let rest for 5 minutes.
3. Thinly slice the steak and place in a large serving bowl. Add
the baby kale, sliced onion, cucumber, tomato and nuoc cham
dressing, toss the salad well and serve. —Paul Qui
