In medium saucepan, heat oil over medium heat. Add garlic, cooking for 30 seconds. Add tomatoes with their juice and bring to a low boil (approximately 5 minutes). Add beans, let simmer for 20 minutes. During this time, cook pasta according to package instructions. Use immersion blender to purée sauce right in saucepan. Transferring to a blender also works. Once tomatoes and beans are puréed, add vinegar, salt, and monk fruit sweetener. Cook an additional 2 minutes to combine all flavors. Sauce is ready to be tossed with pasta.

If you plan to freeze any of the sauce, let cool and store in freezer-safe container to enjoy later.
