This is sometimes called "Chinese" vegetable stew in Thailand, because the vegetables are usually of Chinese origin. You can make substitutions according to what is fresh in your market.

Sometimes I use carrots, rutabegas, kabocha and other squash, long beans, daikon, and onions. I make this according to the seasonal veggies. You need at least 4 different veggies to get the variety of tastes and textures required, but I often use 10 or 12 different veggies. The essential flavor comes from the pork belly. This is a "one dish" meal that is especially wonderful on cool fall or winter nights.
