As a vegetarian, it is always a joy for me to find new types of vegetables in Thimphu. Bok choy heads are available now at some stalls at the "Sunday" market and also at the downtown market (off Norzin lam). I stir-fried the stalks along with garlic, ginger, purple onion (as if there's a choice of onion varieties!) and the small green chillies. It also goes well with soy sauce and lime juice.
