Make this sauce to spoon over our Stuffed Swiss Chard.
Heat oil in a medium, straight-sided skillet over medium heat. Add garlic, and cook until fragrant, about 30 seconds. Stir in tomatoes, salt, and pepper. Cook, stirring occasionally, until tomatoes are soft, about 10 minutes.
Remove from heat, and let stand 10 minutes. Pass through the medium disk of a food mill.
Sauce can be refrigerated in an airtight container up to 3 days. Reheat before serving.
