Mince the garlic and finely grate the fresh ginger.
In a small mixing bowl, whisk together the gochujang, tamari, honey, minced garlic, and grated ginger to create the spicy glaze.
Cut the chicken breast into bite-sized 1-inch cubes.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken cubes to the skillet and sear for 5-6 minutes, turning occasionally until golden brown and cooked through.
Add the broccoli florets to the skillet with a splash of water, then cover with a lid for 2 minutes to lightly steam-saute until tender-crisp.
Pour the spicy glaze over the chicken and broccoli, stirring constantly for 1-2 minutes until the sauce thickens and coats everything evenly.
Place the warm, cooked jasmine rice into a serving bowl.
Top the rice with the spicy chicken and broccoli mixture.
Garnish the bowl with sliced green onions, sesame seeds, and red pepper flakes before serving.
