Heat a large skillet over medium-high heat with the olive oil.
Once hot, add the ground chicken and brown one side for 3-4 minutes until golden brown before breaking apart and fully cooking.
While the chicken cooks, whisk all the sauce ingredients except the scallion greens together.
Once the chicken is fully cooked, add the sauce and cook for an additional 4-5 minutes until the sauce thickens.
Stir in the sliced scallion greens at the end right before serving.
Serve the chicken over rice and garnish with toasted sesame seeds, freshly sliced scallions, and optional yum yum sauce.
