Cheddar Ham Soup

My 8 year old son had to plan and prepare a meal for his Boy Scout requirements and he chose this soup to make tonight. I was proud of him for doing it all (except for chopping the onions!) It's a substantial soup that's perfect for a cold day. Recipe from Taste of Home magazine.

2 cups diced peeled potatoes
2 cups water
1/2 cup sliced carrot
1/4 cup chopped onion
1/4 cup butter, cubed
1/4 cup all-purpose flour
2 cups milk
1/4 to 1/2 teaspoon salt
1/4 teaspoon pepper
2 cups (8 ounces) shredded cheddar cheese
1-1/2 cups cubed fully cooked ham
1 cup frozen peas, thawed (optional)

In a large saucepan, combine the potatoes, water, carrot and onion. Bring to a boil. Reduce heat; cover and cook for 10-15 minutes or until tender. Meanwhile, in another saucepan, melt butter. Stir in flour until smooth. Gradually add the milk, salt and pepper. Bring to a boil; cook and stir for 2 minutes or until thickened. Stir in cheese until melted. Stir into undrained potato mixture. Add ham and peas, if desired; heat through. Yield: 5-7 servings.
