Rub the 1¼ pounds chicken breasts with the seasonings (2 teaspoons smoked paprika, Kosher salt and pepper, 1 teaspoon dried oregano, and 1 teaspoon garlic powder)and 1 tablespoon olive oil (from the 2 tablespoons olive oil). Set aside on the counter while you prepare the veggies.
Heat a large pan with the remaining 1 tablespoon of oil. Add the seasoned chicken and cook for 10-12 minutes, until golden and mostly cooked through. Set aside on a clean plate.
In the same heated pan, add a light drizzle of oil only if the pan looks dry. Sauté the 1 medium onion, 2 medium carrots, and 2 celery ribs for 3-4 minutes. Add the 3 to 4 garlic cloves1 yellow bell pepper, and 1 red bell pepper, and continue to sauté for 2-3 minutes.
Add the 1 cup long grain rice and stir to combine, allowing it to toast for a couple of minutes together with the veggies. Stir in the 14.5 ounces tomato sauce or diced tomatoes and 2 cups low sodium chicken stock.
Return the chicken to the pan and nestle it into the rice. Cover the pan and reduce the heat to low. Simmer for 18-20 minutes, or until the rice is done.
Once the rice is done, stir in the ½ cup sliced black olives and freshly chopped parsley, if desired.
Notes
Let the chicken sit out while you prep so it cooks more evenly.
Cut chicken into bite-sized pieces for a quicker cook.
Dice veggies the same size so they cook at the same pace.
Toast the rice with the veggies for extra flavor and better texture.
Use tomato sauce for a smooth base or diced tomatoes for more texture.
Stick with long-grain rice so the grains stay fluffy and separate.
Keep the heat low when simmering so the rice stays tender and the chicken juicy
