Step 1

Bring a large pot of salted water to a boil. Boil the pasta until it is al dente (start tasting a few minutes before the package recommends: you want it to be tender but still a little firm on the inside). Then drain.

Step 2

Meanwhile, in a large saucepan, place the crushed tomatoes, olive oil, balsamic vinegar, garlic powder, oregano, kosher salt, whole basil leaves and spinach (if using). Bring to a simmer, then cover and simmer 15 minutes.

Step 3

Pour the marinara sauce over the pasta. Garnish with chopped basil. If desired, serve with Parmesan cheese or goat cheese crumbles: but it’s just as good without!
