Rinse the brown basmati rice under cold water, then combine with 0.5 cup of water in a small pot and bring to a boil; reduce heat to low, cover, and simmer for 40 minutes or until tender.
While the rice cooks, slice the chicken breast into bite-sized pieces and season evenly with the sea salt, black pepper, and dried oregano.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes, turning occasionally, until golden brown and cooked through; remove chicken from the pan and set aside.
In the same skillet, add the broccoli florets and sliced red bell pepper, sautéing for 4-5 minutes until the vegetables are tender-crisp.
Add the minced garlic to the vegetables and cook for an additional 60 seconds until fragrant.
Return the chicken to the skillet and toss with the vegetables and fresh lemon juice to brighten the flavors.
Fluff the cooked rice with a fork and divide it into a bowl, topping with the chicken and vegetable mixture.
