2In a large skillet, cook the meat over medium heat until browned. Drain any excess fat.
Add the onion soup mix and hot water to the skillet. Stir well to combine.
Stir in the long grain rice, tomatoes, and sliced mushrooms. Bring the mixture to a boil.
Reduce the heat to low, cover the skillet, and let it simmer for about 20 minutes, or until the rice is tender and the liquid is absorbed.
Sprinkle the shredded cheese over the top of the skillet. Cover and let it cook for an additional 5 minutes, or until the cheese is melted.
Serve hot and enjoy your Cheesy Meat and Rice Skillet!
