Easy Pasta Primavera

3/4 of a 16 oz. box of pasta (I use rotini or ziti)
1/4 cup butter
1 envelope Knorr's vegetable soup mix
1 1/2 teaspoon all purpose flour
2 cups milk
2 TBS grated Parmesan cheese

1. Bring a large pot of water to a boil and add pasta.  Cook till al dente, and drain.

2. In a saucepan melt butter.  Blend Knorr soup mix with flour and milk, and then add to saucepan.  Stir.  Bring to a soft boil, and then reduce heat to low and simmer for 7-10 minutes.  Stir in grated cheese.

3. Toss with cooked pasta and serve.

(This makes enough for all seven of us....I usually serve with a salad and garlic bread.)
