I may do that. My substitute for spaghetti is something called No-oodles which are shiritake noodles made from some weird kind of yam or something that ends up having no calories or carbs. I fry them for a minute to dry them up and crisp them a bit, then add sauce and maybe a meatball or two, let it simmer for another minute and serve topped with cheese. The noodles just soak up the flavors of the meat and sauce so it's a fair approximation of a spaghetti dinner.
Have you tried Spaghetti Squash instead?...................

I’ve had shiritake noodles. Not my thing but I don’t do much pasta anyway.
