Broccoli Cheese Vegetable Soup

4 cups cubed potatoes
1 onion, chopped
2 cups sliced carrots
2 cups chopped celery
3 cups cut-up broccoli

Boil all veggies but broccoli in 2 cups of water for 10 minutes. Add the broccoli and boil for 10 more minutes. DO NOT DRAIN!

Sauce:
1/2 cup margarine (I use butter)
3 tbsp flour
2 cups milk
1 pound Velveeta, cubed
1 teaspoon dry mustard
1/4 tsp. pepper
3 chicken boullion cubes

In saucepan, melt butter. Stir in flour. Add milk and cook, stirring constantly, until thick. Add cheese and other ingredients. Mix until smooth. Add to undrained veggies and heat together, but do not boil.

(I also like to add diced, cooked chicken sometimes for a full balanced meal!)
