Prep all your vegetables. In a large pot with a lid, heat the oil over a medium-high flame. Add the onions and garlic and saute until the onions are translucent, about 5 minutes. Add the jalapeno and potato slices, and the salt and pepper. Saute until all the vegetables are soft, about 10 minutes. Add the tomatoes and bay leaves and crushed red pepper flakes cook until the mixture bubbles, then reduce heat to low and cover with a lid. Simmer for an hour stirring every 10 minutes.Remove and discard the bay leaf. Season the sauce with more salt and pepper, to taste. Let cool for a few minutes (10 minutes) and then pour entire contents of pot into food processor and process until smooth and creamy looking-it will be a bright orange red color! Store in an airtight container in the fridge for up to 2 weeks.
