Add some olive oil to a saucepan over medium-high heat. (A little more than what’s necessary to just cover the bottom).
Add the red pepper flakes and garlic and gently simmer for a minute or two.
Add the tomatoes. If using whole tomatoes, crush them with your hands.
Bring the sauce to a gentle simmer and season with salt and pepper.
Add the basil.
Simmer for 15 minutes or until your desired consistency is achieved.
