Chef's Notes

  • The Vegetable, Black Bean, and Wild Rice Stuffed Pepper recipe calls for 3 1/2 cups of Tomato Sauce. Store the remaining sauce in an airtight container in the refrigerator.Fun fact: canned tomatoes are richer in lycopene than fresh tomatoes. Lycopene, a natural plant compound, has numerous health benefits and gives tomatoes their gorgeous hue.
