02 - Heat olive oil in a large skillet over medium heat. Add garlic and sauté 30 seconds, until fragrant.
03 - Stir in crushed tomatoes, sugar, oregano, red pepper flakes, salt, and pepper. Simmer for 8–10 minutes, stirring occasionally, until slightly thickened.
04 - Add ravioli to the boiling water and cook according to package instructions (typically 3–4 minutes), until they float to the surface. Drain gently.
