Preparation:
With a sharp knife, cut peel and all white pith from the oranges. Working over a large bowl, cut between the membranes to release segments. Cut each segment into 3 or 4 pieces. Add the cucumber, dried cranberries, fresh cranberries, onion, orange juice, vinegar, salt and red pepper. Cover and refrigerate from 1 to 4 hours. Just before serving, gently mix in avocados and cilantro.
