In a small saucepan, cook rice according to the package's directions.
Place a large cast iron skillet over medium-high heat. Once the skillet is hot, add the oil. After the oil shimmers, add the sausage and cook until browned on both sides, about 5 minutes. Remove from the pan and set aside.
Add the peppers and onion; sauté for 4-5 minutes. Add the garlic, salt, and pepper, and cook until fragrant, about 1 minute. Remove from the pan and set aside with the sausage.
Add the tomato paste and about ¾ cup of chicken broth, and whisk to combine. Allow the mixture to simmer for 1 minute, then add the paprika and cayenne.
Stir in the cooked rice, sausage, remaining chicken broth, pepper, and onions until combined. Garnish with chopped parsley and serve immediately.
