Step 1

Place a large skillet over medium-high heat. While the skillet heats up, place chicken chunks in a bowl and toss with 1/2 Tbsp. arrowroot starch, salt, and pepper.

Step 2

When skillet is hot, add 1 Tbsp. oil and reduce heat slightly. Add chicken and cook for 2-3 minutes without stirring. Flip chicken pieces when they release easily from the pan and are lightly browned. Continue cooking until chicken is almost cooked through. Transfer chicken to a plate and return pan to medium-high heat.

Step 3

Add 2 tsp. oil to hot pan then add sweet onions and carrots. Sauté, stirring frequently, 4-5 minutes or until vegetables start to soften.

Step 4

Add bell peppers and continue to cook an additional 5-6 minutes, stirring frequently.

Step 5

While the veggies are cooking, combine ketchup, rice vinegar, garlic powder, and dried ginger. In a separate bowl, whisk 1 Tbsp. arrowroot starch into pineapple juice, then whisk this into the ketchup mixture to make the sauce.

Step 6

When veggies are crisp-tender, add chicken and pineapple chunks to the pan. Add sauce and cook, stirring, 1-2 minutes or until sauce thickens.

Step 7

Remove from heat, sprinkle with sliced green onions and sesame seeds, if using.
