Smear a thin layer of prepared masa on each corn husk.
Add a small amount of shredded chicken to the center of the masa.
Spoon salsa verde over the chicken, being careful not to overfill the tamale.
Fold one side of the corn husk in.
Fold the other side in.
Fold the pointy top to the center of the tamale.
Set standing up while assembling the other tamales.
Repeat until there are no more corn husks left.
Add 2 cups of hot water to a steamer pot.
Add the insert and place some corn husks on the insert.
Arrange the uncooked tamales upright in the steamer.
The tamales should be standing with the open side up.
Cover and cook on low for 1 ½ to 2 hours.
Turn off the heat and let the pot stand covered for 30 minutes.
The tamales are ready when masa peels away from the corn husks easily.
