Fettuccine with Butter, Anchovies, and Onions

6 tbs butter
4 onions, quartered and thinly sliced
1 can anchovy fillets, drained
1 1/2 tbs parsley
1 lb pkg fettuccine
salt and pepper, to taste
Warm the butter in large skillet and add the onions. Saute gently until lightly colored, about 12 minutes. Transfer the onions to a dish. Add the anchovies to the pan and heat just until they begin to dissolve into the butter. Do not let them harden. Return the onions to the pan, then stir in the parsley. Cook fettuccine according to directions. Drain, reserving a little of the cooking water. Toss the pasta in the skillet with the onion sauc. Add some of the pasta water, if ne3cessary, to moisten. Sprinkle with plenty of pepper, and serve. 4 servings = about 830 calories.
