If I could tick both boxes I'd go for meat sauce and meatless....sorry, for me meatballs and pasta don't really go together.
But we don't actually eat spaghetti very often though - for light, delicate dishes such as Carbonara or Aglio e Elio I prefer to use linguine, and for more robust sauces like a Ragu I'll use either fettuccine or tagliatelle.
I have a whole cupboard full of pasta, so this thread actually prompted me to do a quick audit of my pasta cupboard as I wasn't sure what I had in there

Turns out I do have a couple of packets of spaghetti: one tricolore and one squid ink. I have a lot of Barilla at the moment because it was on offer at Ocado a couple of months ago so I stocked up, and the more interesting ones (the unusual shapes and the squid ink) are what's left from the souvenirs we brought back from our latest holiday.
