Cut chicken into 2-inch chunks, then throw them into a large freezer bag. Add 1/2 cup corn starch, seal the bag, and shake it all up!
Place a large skillet on the stove on medium high heat, then add 2 tablespoons sesame oil. Add the coated chicken and saute until chicken is lightly browned (not cooked through).
Add chicken to crockpot and throw veggies on top.
In a small bowl or measuring cup, whisk cold broth and 2 tablespoons of cornstarch until fully dissolved. Then add 2 teaspoons sesame oil, honey, soy sauce, and rice vinegar. If needed, heat honey a bit in the microwave before adding to make sure it's runny.
Pour mixture over chicken and veggies, stir just enough to make sure it gets to the bottom.
Turn the crockpot on to low for 2-3 hour, depending on how soft you like your veggies. Serve warm over your choice of cooked rice. Sprinkle with sesame seeds if desired.
