Step 1

In a large skillet, heat the oil over medium heat. Add the chicken, and cook for 5 to 7 minutes, or until cooked through and browned. Remove from the heat.

Step 2

In a small saucepan, stir together the broth, orange zest and juice, sugar, and soy sauce. Bring to a boil, then reduce the heat to a simmer, and cook for 8 to 10 minutes, or until thickened slightly.

Step 3

Pour the mixture over the chicken in the skillet. Mix well to coat.

Step 4

In a medium pot, combine the broccoli, carrots, and about '/ cup water. Place over medium-high heat, and cook for 5 minutes, or until tender. Divide among 4 bowls, and top with the chicken, scallions, and sesame seeds.
