Adapted from Cook's Illustrated
2 large cloves garlic, minced
2 tablespoons olive oil
1 28-oz. can crushed tomatoes (I use Cento brand)
Salt and pepper
Heat garlic with oil in saucepan over medium heat. When garlic starts to sizzle, add tomatoes. Simmer, uncovered, until sauce is thick enough to mound on spoon, about 15 minutes. Season to taste with salt and pepper.
