Saute the ground beef in a saucepan or skillet over medium high heat until completely browned. Drain the excess fat. 

Add the powdered cheese mix and noodles from the Kraft mac and cheese box to the skillet or saucepan. Stir to combine well. 

Place the tomatoes, milk, frozen corn, frozen peas and salt to taste. 

Cover, bring to a boil and then simmer for 12-15 minutes until the noodles are tender. 

Top with the shredded cheese, allow to melt and serve.
