pesto with penne and nothing else is a very good meal

i want my spicie meatballe. how can i enjoy my penne without my spicie meatball?

I have always preferred Pesto and Gnocchi alone as a meal

so is a pack of Marlboros

Except that that alone, has no nutritional value. If you put no other type of vegetable or type of healthy sauce (like tomato), then you're basically eating something equivalent to a big mac.
