You can be more generous with the olive oil, it will taste better.
Added frozen basilic leaves (way to keep them fresh)
Added extra basilic spices (Never enough)
Parmesan powder + nutritional yeast (not an obligation, i'm just vegetarian and I had it)
Oignons and mushroom.
Slow cook the ingredients + pasta with the olive oil will taste better.
Parmesan at the end.
