Easy Tomato Sauce with Fried Egg

This is as easy as tomato sauce gets! I got the recipe from Smitten Kitchen. Serves 4.

1 28 oz can of whole peeled tomatoes
5 tablespoons butter
1 onion, peeled and cut in half
salt to taste

spaghetti
Parmesan cheese
4 eggs

Put the tomatoes, onion, and butter in a saucepan over medium heat. Bring it to a simmer, then lower the heat and keep it at a slow simmer for 45 minutes. Stir occasionally, crushing the tomatoes and breaking them apart with a wooden spoon. Remove from heat, discard the onion (weird, huh?), add salt to taste.

Prepare spaghetti according to package directions; fry the eggs according to preference. Serve the sauce over the noodles topped with Parmesan and a fried egg.
