This tender Wat Tan Gai Choy (Stir Fry Mustard Greens in Silky Egg Sauce) is…
Rehash your roast pork and leftovers in this popular Chai Boey (Mustard Greens Stew). It is a spicy and tangy soup delicious served with steamed rice.
If you ever have a bunch of leftovers and don’t know what to do with it, make Chai Boey (Mustard Greens Stew). This amazing spicy and tangy stew can incorporate all the flavors and still turned out delicious. Of course some leftovers like roast meats and stir fry vegetable work better than others. Like my mom, I am a little more selective of the kinds of dishes I throw into the mix but there really is no rule as to what can or cannot be included.
That said, Chai Boey is usually cooked “fresh” at our house. The only “leftover” I put in is Siew Yoke (Roasted Pork Belly). In fact, I usually make extra roast pork belly just so I have a little “leftover” for this stew. Often times I have to add in a little raw pork belly or pork shoulder to make up for the amount needed to give this stew sufficient flavor.
Besides roast pork belly, the other pertinent ingredients are kiam chai (pickled mustard greens), gai choy (tua chai/mustard greens), dried chilies, and dried assam gelugor (assam keping/tamarind slices). If you prefer a more spicy and tangy stew, add a few more dried chilies and assam gelugor. This recipe is very forgiving and the ingredients listed here are more of a guide. Please adjust accordingly.
I added some plum tomatoes into the stew to give it a little color and a tad more tartness. Sometimes, I also like to throw in a few fresh red chilies.

Chai Boey (Mustard Greens Stew) goes really well with steamed rice. Did I mention sambal belacan? It is to die for with our “beloved” Sambal Belacan. Be sure to cook a little extra rice so that everyone is satisfied. 😉
