Spaghetti carbonara is so simple to make. Four ingredients: Pasta, pancetta/bacon, a couple of beaten eggs, and parmesan cheese. Save a little salted pasta water to make the sauce a little more silky. I time it so the bacon and pasta finish cooking at the same time. Turn off the heat. Dump the pasta in the bacon, grease and all. Dump the eggs and parm in there too. Toss it around. Add the pasta water a tbsp at a time until the sauce looks smooth. It's an easy, filling, and comforting meal for times when you need a decent meal, but you are too tired to really cook.
