Separate the leaves of radicchio to make individual cups. Set aside.

Remove skin from trout and flake into a medium sized bowl. Add red onion and orange sections. Lightly toss to evenly combine.

In a small bowl, combine all the orange juice, honey, lime juice, cilantro, salt and pepper. Whisk to combine. Slowly add oil while whisking vigorously. Pour vinaigrette over the prepared salad and gently toss.

Place each portion of salad into the individual radicchio cups. Serve chilled.

Note: This dish can be prepared up to four hours ahead of time.
