In your large skillet or pot, over medium heat, add the Italian sausage. Using a wooden spoon, break it apart as it cooks. Sauté until it is nicely browned and fully cooked, about 5-7 minutes.
Once the sausage is browned, add the minced garlic and dried minced onion flakes to the skillet. Cook for an additional minute until fragrant, stirring to combine the flavors.
Sprinkle in the Italian seasoning, stirring to coat the sausage mixture evenly. This step enhances the aroma and flavor, setting the stage for the sauce.
Pour in the water and the two cans of tomato sauce. Stir everything together, ensuring that the sausage is well-distributed in the sauce.
Bring the mixture to a gentle simmer. Allow it to cook for about 10 minutes, letting the flavors meld together beautifully.
Stir in the cooked rice, mixing thoroughly to combine with the sauce. Cook for an additional 5 minutes, or until everything is heated through.
Remove from heat and serve hot. Sprinkle cheese on top of each serving, allowing it to melt slightly before enjoying.
