Mix together in a bowl the ground chicken, spices, egg, and green onion until combined. Add the cornstarch and mix.
Put about 1tsp meat mix in the middle of the skin and fold over and press sides to adhere. Please see photos above. Take the 2 pointy ends and press them together in front of the wonton.
I steamed my dumplings in the instant pot for 4 minutes on the steam function. I steamed them in batches because I have a small 3qt instant pot that maybe only fit 10 wontons at a time. Cook the wontons before storing in the refrigerator because if you store raw wontons in the refrigerator the meat juice will seep out and make a mess. You can also steam in a traditional stovetop steamer for about 20 minutes.
Eat the wontons as is after cooking or add them to soup. They are delicious on their own with some coconut aminos to dip them in.
