Sauté the Sausage. Heat olive oil in a large skillet over medium heat. Add sliced smoked sausage and cook until browned on both sides, about 5 minutes. Remove and set aside.
Cook the Aromatics. In the same pan, add diced onion, garlic, and bell peppers. Sauté for 3-4 minutes until softened and fragrant.
Toast the Rice. Stir in uncooked rice, letting it absorb the flavors and lightly toast for 1-2 minutes. This helps prevent mushy rice.
Add the Liquids & Seasonings. Pour in chicken broth, diced tomatoes, tomato paste, and seasonings. Stir well to combine. Return the browned sausage to the pan.
Simmer Until Cooked. Bring everything to a simmer, then cover and cook for 15-20 minutes until the rice is tender and the liquid is absorbed. Stir occasionally to prevent sticking.
Garnish & Serve. Once the rice is fully cooked, fluff with a fork and stir in fresh green onions or parsley. Serve hot and enjoy.
