2 cups peeled and diced potatoes
1/2 cup diced carrots
1/2 cup diced celery
1/4 cup chopped onion
1 teaspoon salt
1/4 cup butter
2 cups milk
1/4 cup all-purpose flour
2 (15 ounce) cans whole kernel corn, drained
2 1/2 cups shredded Cheddar cheese
Place potatoes, carrots, celery, onion and salt in a large pot with water to cover. Bring to a boil, reduce heat and simmer 20 minutes.
Meanwhile, combine butter, milk and flour in a small saucepan over medium-low heat. Stir constantly until smooth and thick.
Pour milk mixture into cooked vegetables. Stir in corn and cheese until cheese is melted. Serve.
Note: I have done this with the Steam and Mash potatoes found in the frozen veggie isle. Just don't add them until the last 5-10 minutes of the first step.
