These are like boiled gyoza, or wonton dumplings. made these in a hurry and this is how they turned out. You can make these in no time.
It's a bother to make gyoza dumplings so make them with ground chicken and chopped leek.
I just added sesame seeds, but they're also delicious with chopped shiso leaves. They're very simply flavored, so you could try various sauces with them.
Enjoy Japanese food around the world.
