Season the chicken breast evenly on both sides with sea salt, black pepper, and dried oregano.
Heat 1 tbsp of olive oil in a large skillet over medium-high heat.
Place the chicken in the skillet and sear for 6 to 7 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest for 3 minutes before slicing.
In the same skillet, add the remaining 1 tbsp of olive oil and the minced garlic, sautéing for 1 minute until fragrant and golden.
Pour in the chicken broth and scrape the bottom of the pan to release the browned bits, creating a simple garlic pan sauce.
Steam the broccoli florets until they are tender-crisp and bright green.
Warm the cooked white rice and black beans, then assemble the bowl by topping the rice and beans with sliced chicken and broccoli.
Drizzle the garlic pan sauce over the entire bowl and serve immediately.
