This is one of those easy, weekday dinners. When you come home tired and crave a warm, comforting meal, but at the same time you want it to be at least a bit healthy. It takes literally 10 minutes to do the sauce, so make sure to start with cooking the pasta, then both the pasta and the sauce will be ready at the same time.
Spinach may not bring good memories to some people, but even Karl loves that sauce (despite childhood cafeteria spinach trauma). Definitely worth a try!
