Heat 1 tablespoon of olive oil in a large skillet over medium heat.
Add the diced onion and garlic, cooking until they become translucent.
Add the sausage to the skillet.
Cook until it browns, breaking it up with a spatula or spoon as it cooks.
Once the sausage is cooked, add the bell pepper and remaining olive oil.
Cook for an additional 3-4 minutes to soften the peppers.
Add the rice to the skillet, stirring well to coat all grains with the oil and sausage mixture.
Pour in the chicken broth, salt, black pepper, and oregano.
Bring the mixture to a boil, then reduce the heat to low.
Cover the skillet and let it simmer for about 20 minutes, or until the rice is tender and has absorbed all the liquid.
