- ¼ teaspoon black pepper
- ¼ teaspoon ground cumin
- 2 cups low-sodium chicken broth
- 1 cup tomato salsa
Other
- 1 cup long-grain white rice, rinsed
- 1 cup shredded mozzarella cheese
Instructions
- Cook the sausage: Heat a large skillet over medium-high heat. Crumble the ground Italian sausage into the skillet and cook until it begins to brown, breaking it up with a spoon as it cooks.
- Cook the vegetables: Add the chopped bell peppers and finely chopped onion to the skillet. Cook for about 5 minutes, stirring often, until the vegetables are crisp-tender.
- Add spices and garlic: Stir in the minced garlic, salt, dried oregano, black pepper, and cumin. Cook for 1 minute to release the flavors.
- Add broth and salsa: Pour in the low-sodium chicken broth. Use a wooden spoon to scrape any browned bits from the bottom of the skillet to incorporate those rich flavors. Stir in the tomato salsa evenly throughout the mixture.
- Prepare and add rice: Rinse the long-grain white rice thoroughly under cold water, then drain it well. Add the rice to the skillet and stir to combine with the sausage and vegetable mixture.
- Simmer the casserole: Bring the mixture to a simmer. Cover the skillet, reduce the heat to medium-low, and let simmer gently for 15 to 20 minutes until the rice is fully cooked and tender.
- Melt the cheese: Sprinkle the shredded mozzarella cheese evenly on top of the casserole. Cover the skillet again and let the cheese melt, then serve warm.

- Using low-sodium chicken broth helps control the saltiness and make the dish healthier.
