Begin by rinsing the brown rice under cold water until the water runs clear. In a medium-sized pot, combine the rinsed rice with 4 cups of water and a pinch of salt. Bring to a boil, then reduce heat to low, cover, and let simmer for 40-45 minutes until tender. Fluff the rice with a fork and set aside to cool.
In a large skillet, heat the olive oil over medium-high heat. Add the diced chicken breast and season with salt and black pepper. Sauté for 7-10 minutes, stirring occasionally, until golden brown and cooked through.
Once the chicken is cooked, pour the teriyaki sauce over it in the skillet. Stir thoroughly to coat all chicken pieces. Allow to simmer for an additional 2-3 minutes to thicken the sauce.
In a separate pan, heat more olive oil if necessary and add the broccoli florets, sliced red bell pepper, and julienned carrots. Cook over medium heat for about 5-7 minutes until vibrant and slightly tender yet crisp.
For meal prep containers or bowls, evenly distribute the cooked brown rice at the base. Top each serving with the teriyaki chicken followed by the sautéed vegetables.
Finish each bowl by sprinkling sesame seeds and adding sliced green onions on top.
Allow the assembled bowls to cool completely at room temperature before sealing with lids. Store in the refrigerator for up to 5 days.
