A bag of onions and a jar of minced garlic punch above their price tag for pasta enhancement as well.

I like to saute the onion (diced) until golden and translucent, then add a scoop of the minced garlic, then just as it starts to brown, dump in the sauce, Italian seasoning, and stir at a very low simmer while the noodles cook.

Add some pasta water to the sauce before you strain so it sticks to the noodles better.
