This is my go-to sauce for easy one-bowl dinners. Get tomatoes, kale, nuts, and fruit all in one super sauce. The chopped walnuts and chipotle make it hearty with very little fat and no cholesterol. Serve this super sauce tossed with hot whole-wheat noodles or ladle it over gluten-free options such as quinoa, barley, or baked potatoes. The sauce costs just $2.17 per serving using organic ingredients. Add organic whole-wheat pasta and top with nutritional yeast for a $2.37 meal.
