Whirl flour with salt in a food processor and with the motor running slowly pour in the water. Mix until water is added and you can tell the mixture is coming together into a dough. Add onions and whirl until just mixed and turn onto a generously floured surface. Roll into two even balls and shape each into a disc and wrap tightly in saran wrap. Refrigerate for 1 hour before proceeding OR refrigerate up to 1 day and make ahead.
Preparing the sauce is easy. Simply mix all ingredient together with a fork or whisk and refrigerate. This sauce will keep well, covered, for up to a week.
Bring a large pot of water to the boil and then add the bok choy/greens to the pot for a minute or two just to blanch. Remove and put them in a bowl of ice water and drain. Dry the greens. If making ahead, the greens will keep well, covered and refrigerated, for up to a day.

An hour before serving ensure the steaks are out of the fridge and coming to room temperature. Sprinkle steaks with salt and pepper.
To prepare the pancakes after your dough has rested for at least one hour cut each disc into three and shape into thin panckaes on a floured surface. Stack the pancakes between layers of parchment paper and heat oil in frying pan over medium heat. Cook one pancake at a time until golden, about 2 to 4 minutes per side. Remove to a paper-towel-lined plate and repeat with remaining pancakes, adding more oil as needed. Keep warm in the oven and cut each into 6 wedges to serve.
For steak, heat oil in a large grill or frying pan (I used a cast iron pan) over medium high heat. When oil is shimmering add steak and cook until seared and medium rare, 3 to 4 minutes per side. Steak may need to be cooked in batches so as not to overcrowd the pan. Let rest for 15 minutes and then thinly slice to serve.
The final step while your steak is resting is to saute the greens. Heat oil in a large frying pan on medium high heat. Add garlic and then greens and saute until warm and coated, about 3 minutes.
Serve sliced steak, pancakes and greens with sauce for dipping. Enjoy!
