Prep the vegetables - Shred the cabbage, slice the bell pepper in to 1-2 inch strips, tear radicchio into bite-sized pieces (if using). Slice the shallots and garlic, and set aside. Slice the jalapeno and shake out most of the seeds.
Assemble the salad - Combine the cabbage, shredded chicken (if using in lieu of parts), bell pepper, radicchio (if using), and herbs in a large bowl.
Crisp the shallots and garlic - Heat the oil over medium-high heat. Add the shallots and sauté until translucent, then add the garlic. Fry until golden, stirring constantly to prevent scorching. Pour the oil into a measuring cup through a strainer, catching the shallots and garlic to drain.
Finish the dressing - After the oil has cooled slightly, add 1 T lime juice, 2 T fish sauce, ½ t salt, ¼ t pepper, 1 t sugar, jalapeno, and 1 T apple cider vinegar.
Toss and Serve - Pour the dressing over the salad, tossing to coat. Serve topped with the fried shallots and garlic.
Notes
I prefer this salad with shredded chicken breast tossed into the mix, but Ron loves chicken parts, especially dark meat. So I just roast chicken thighs and legs in advance in the air fryer for him.
