Rib eye / New yolk steak
Sprinkle with salt & pepper both sides with a dash of fish sauce.
Sous vide @ 129 - 130 (for medium rare)x 1.5 hour, then sear both sides (or just grill the steak / pan fry, whichever method you prefer) let rest 10 mins, cut  into thin slices.

Prep: Cucumber / tomatoes / cilantro / purple onion / romaine lettuce:

For the sauce:
