Cook the pasta per instructions in a large pot of salted boiling water. Drain, making sure to reserve 1 cup of the cooking water.

While the spaghetti is cooking, heat the olive oil in a large skillet over medium heat. Add the tomatoes, oregano, and crushed red pepper flakes along with some sea salt and freshly cracked pepper, to taste, to the hot pan and cook, stirring occasionally, for 3-4 minutes, or until nearly bursting.

Add the minced garlic, and cook, stirring constantly for 30 seconds.

Add the drained spaghetti along with 1/4 cup reserved cooking water, or more if needed; allow to simmer for a couple of minutes, to thicken.

Add the spinach; season with sea salt and freshly cracked pepper, to taste, cook, tossing with tongs occasionally, for 2 minutes or until the spinach is wilted.

Pour the pasta into a serving bowl and toss it with fresh basil. Serve with lots of Parmesan cheese on the side. Enjoy.
