Add the ground chicken, increase heat to medium-high, and cook until the chicken is browned and no longer pink.
Add the chili powder, cumin, coriander and oregano. Stir to evenly distribute the spices throughout and onto the ground chicken.

Bring to a boil, then reduce heat to low and simmer uncovered for 15-20 minutes or until the liquid has reduced and thickened.
