We like to prepare these by "steam-frying" as is done for classic pot stickers. Add a bit of oil (maybe part canola and part toasted sesame) and place dumplings flat side down, when bottom is lightly browned, add a splash of chicken broth and cover pan to finish cooking (when the dumpling skin turns from pasty white to translucent, it's probably done.

Add a dumpling sauce (a mixture of rice wine vinegar, tamari, a bit of water, some finely minced garlic and lots of grated ginger, some sugar (coconut or brown sugar will deliver more flavor), and lots of thinly sliced scallion!
