Heat large skillet over medium high heat. Once hot, add oil.
1 tablespoon oil
Add the chicken chunks, and saute chicken on medium high heat until cooked through, stirring periodically.
1 1/2 pounds boneless
Remove chicken from skillet, and set aside for later. Saute minced garlic until fragrant, then add soy sauce, honey, peanut butter, and lemon juice and bring to boil.
2 cloves garlic, 1/3 cup soy sauce, 1/2 cup honey, 1 tablespoon peanut butter, 1 tablespoon lemon juice
Keep at a low boil for 7-10 minutes until it starts to thicken.
Make cornstarch slurry with 2 teaspoons cold water, and add to sauce while stirring. Cook another 2-3 minutes until thickened enough that a spoon drawn through it leaves a streak.
1 tablespoon cornstarch
Return chicken to the pan and stir to coat.
Serve immediately over rice or couscous, topped with sesame seeds.
