In a large mixing bowl, combine the ground beef or chicken, breadcrumbs, finely chopped green onions, lightly beaten egg, minced garlic, and grated ginger. Mix thoroughly until all ingredients are evenly incorporated.
Shape the mixture into small meatballs, around 1 inch in diameter. Place each meatball onto a baking sheet lined with parchment paper, ensuring they have some space between them.
Transfer the baking sheet to the preheated oven and bake for 15-20 minutes, or until the meatballs are fully cooked and browned on the outside.
While the meatballs bake, prepare the teriyaki sauce. In a small saucepan, combine the soy sauce, brown sugar, rice vinegar, and sesame oil. Heat over medium heat, stirring occasionally, until the sugar has dissolved. Reduce the heat to low and allow the sauce to simmer gently for a few minutes, thickening slightly.
In a separate pot, steam or boil the broccoli florets and julienned carrot for about 5-7 minutes until they are tender yet still crisp. Drain and set aside.
Once the meatballs are done baking, remove them from the oven and carefully toss them in the teriyaki sauce until they are evenly coated.
To create your rice bowls, start by scooping a generous portion of the cooked jasmine rice into each bowl. Top the rice with an equal number of teriyaki-coated meatballs, followed by the steamed broccoli and julienned carrots. Drizzle any leftover teriyaki sauce over the top for added flavor.
Finish off your bowls by sprinkling sesame seeds over the top and adding additional chopped green onions for a burst of freshness.
