Start by heating the vegetable oil in a large skillet over medium heat.
Add the ground sausage and cook it until it's completely browned, breaking it up with a spoon.
Add the chopped bell pepper, onion, and minced garlic to the skillet with the sausage.
Cook for about 10 minutes, or until the onions are soft and translucent.
Stir in the cayenne pepper, paprika, black pepper, and salt.
Mix everything well to coat the vegetables and sausage with the spices.
Fold in the cooked white rice.
Mix thoroughly so that the rice is evenly distributed and well-coated with the sausage mixture.
Allow the rice to cook for another 5 minutes, stirring occasionally.
This ensures the flavors meld together nicely.
