Brightly sweet kiwi provides a vibrant counterpoint to the salty pancetta, spicy jalapeno, and rich, buttery avocado in this uniquely tasty dish. A drizzle of balsamic glaze provides the perfect finishing touch. Most of the avocado sold in supermarkets is still in its unripened stage. To ripen, place avocados in a paper bag and set aside at room temperature for 2-4 days. When the fruit is soft to the touch, it is ready for use.
