Heat the olive oil in a large skillet over medium-high heat. Add the diced chicken and season with salt, pepper, and paprika. Cook until browned and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set aside.
In the same skillet, add the diced onion and bell peppers. Sauté for about 3-4 minutes until the vegetables are tender.
Stir in the minced garlic and cook for an additional minute until fragrant.
Add the rice to the skillet, stirring to coat with the oil and vegetables for about 2 minutes.
Pour in the chicken broth and add the dried oregano. Bring the mixture to a boil.
Reduce the heat to low and return the cooked chicken to the skillet. Cover and let simmer for about 15 minutes, until the rice is cooked and has absorbed the liquid.
Stir in the frozen peas, cover, and let it cook for another 5 minutes, or until the peas are heated through and the rice is fluffy.
Adjust seasoning if necessary, then remove from heat.
Notes
Serve directly from the pan for a rustic feel, garnished with fresh parsley.
