Linguine with Swiss Cheese, Ham and Peas

8 oz. linguine (I use Dreamfields)
2 T butter or margarine
2 T flour
1 c milk
dash salt
dash pepper
dash nutmeg
1 c grated Swiss cheese
1 c diced cooked ham
1 c frozen peas, thawed

Cook linguine according to package directions; drain. In a large pot, melt the butter. Add flour and whisk till smooth. Cook over low heat for 2 minutes. Add milk, salt, pepper, and nutmeg. Continue to cook, stirring, until thickened. Add cheese and stir until cheese is melted. Add ham and peas. Add hot cooked pasta and toss. If the pasta has just come from the pan, serve immediately. If not, then heat over very low heat until hot throughout. Makes 4 servings.
