Spaghetti Carbonara

Spaghetti
1# bacon
3 TBSP butter
3/4 C Parmesan cheese
1 small onion, thinly sliced
2 eggs, beaten
parsley
black pepper

Cook spaghetti, and drain. While spaghetti cooks, fry bacon until desired crispness, drain on paper towels. Clean pan of all bacon drippings. Melt butter and saute onions. When the onions are still somewhat crisp, move them to one side of the pan, and add spaghetti. Move onions to the top of spaghetti. Put 1/2 the cheese on top, then drizzle the beaten eggs over all. Toss with 2 forks and continue cooking on medium low heat. The eggs and cheese mixture will coat the spaghetti. When dry, add the bacon and toss to warm. Sprinkle the remaining cheese over top, and add parsley for color and black pepper to taste.
