Cut the chicken breast into bite-sized cubes and season with sea salt, black pepper, garlic powder, and ginger powder.
Heat the olive oil in a large non-stick skillet or pot over medium-high heat.
Add the chicken to the skillet and brown for 4-5 minutes until golden on all sides, then remove and set aside.
In the same skillet, add the diced red onion and chopped bell pepper, sautéing for 3 minutes until softened.
Stir in the tomato puree, smoked paprika, and dried thyme, cooking for 2 minutes to allow the flavors to deepen.
Add the parboiled rice and chicken broth to the skillet, stirring to combine and scraping up any browned bits from the bottom.
Bring the mixture to a boil, then return the chicken to the pot, reduce heat to low, cover, and simmer for 18-20 minutes.
Once the rice is tender and liquid is absorbed, fold in the fresh spinach until wilted and serve immediately.
