Prep and marinate chicken - Slice chicken against the grain into 1/2" / 1.2 cm slices. Whisk together all ingredients listed under marinade. Pour over chicken and allow to marinate in refrigerator for at least 30 minutes or overnight. (Can be done up to 1 day ahead)
Make vinaigrette - Mince garlic. Whisk together garlic, honey, aminos, rice vinegar and sesame oil. Slowly add oil while whisking. (Can be done up to 5 days ahead and refrigerated)
Red peppers / Oranges / Green onions - Prep as directed. (Can be done up to 3 days ahead)
Heat a saute pan or wok over medium heat. Add oil. When oil begins to shimmer, use tongs or a slotted spoon to transfer chicken to the pan (be careful - the hot oil may sizzle a bit). Reserve marinade. Cook chicken without stirring until the bottom begins to brown, ~5 minutes. Use a spatula to flip chicken over and cook the other side. When chicken is nearly cooked through, add remaining marinade and sesame seeds and continue cooking until marinade thickens and coats chicken.
Assemble salads by tossing salad greens with cashews, red peppers, cucumbers and oranges. Top with sesame chicken and green onions. Drizzle dressing over the top just before serving and enjoy!
