In a medium saucepan, combine water & condensed soup, frozen peas & hotdog pieces. (You can cook the hotdogs in the microwave to save time). Heat over medium-low heat until peas are tender (about 10 minutes). Remove from heat. Stir in mozarella cheese until melted. Pepper to taste.
Add a dollop of salsa & sour cream for a spicier flavor.
Please note that, if there are left-overs, the rice will absorb most of the soup, so you will have to add more water.
