Add the undrained diced tomatoes, oregano, basil, salt, pepper, red pepper flakes, chicken broth, and tomato paste. Let it simmer for about 5 minutes.

Let the sauce simmer on low, uncovered, while you boil the pasta according to package instructions. Keep an eye on the sauce, stir it occasionally, and cover it if it reaches your desired level of thickness.
