Preheat your oven to 400ºF and line two quarter sheet pans with parchment paper.
Add the broccoli to one pan and toss with 1 tablespoon of olive oil and generously season with salt and pepper. Place the chicken on the other sheet pan.
Bake both pans on the middle rack for 20-25 minutes or until the broccoli is vibrant green and browning around the edges, and the chicken is crispy golden brown. (You may need to pull the broccoli out of the oven a few minutes before the chicken.)
In the final 10 minutes of baking, mix together the sauce ingredients and add to a pan over medium heat. Once the sauce begins to thicken and coats the back of a spatula, toss the crispy chicken in the sauce.
Serve the chicken and roasted broccoli over the rice blend and garnish with sliced green onion and toasted sesame seeds.
Notes
My go-to brands for lightly breaded frozen chicken breast are Perdue, Tyson, Kirkland Signature, Just Bare, and Realgood Foods. You can also use homemade chicken breast bites or popcorn chicken.
