Beef with Bok Choy and GInger

I stumbled upon this recipe by simply using the ingredients I have on hand. I am certain this is a variation of some popular recipe I may not be even aware of as I cook based on what I recall long ago.

Beef
3 heads of bok choy, cut thinly, stems removed
Onion
Ginger, cut finely
Oregano
Basil
Thyme
Olive oil
Garlic
Worcestershire sauce

1. Rub the beef with Worcestershire sauce and spices. Allow to sit.
2. Place olive oil on the slow cooker, followed by the bock choy, garlic, ginger, onion. Coat the bok choy with olive oil.
3. Place the beef and cover with the bok choy.
4. For 1 pound, cook on High for 3 hours.
