1 lb. box pasta, cooked and drained
1 c milk
2 tablespoons butter/margarine
1/4 c flour
1 teaspoon dry mustard
1/2 teaspoon garlic salt
1/4 teaspoon pepper
1/2 c parmesan
1 c shredded cheddar
1/2 tablespoon worchestershire sauce
heat milk and butter over medium heat until melted. whisk in flour, mustard, salt, and pepper. keep stirring until slightly thickened. add cheeses and stir constantly till melted and smooth. whisk in worchestershire sauce last. pour over pasta and toss to coat. serves 6.
* tip: the longer you let the sauce cook, the thicker it'll be. if you like it runny, turn the heat off immediately after adding the cheese - it'll still be warm enough to melt it completely. i let mine cook for about 5 minutes and it ended up a little thicker than i liked, so i added a little water.
