In a large bowl add the avocado oil, rice vinegar, cilantro, sesame seeds, low sodium soy sauce, honey, sesame seed oil, red pepper flakes, coarse kosher salt, and black pepper. Mix until combined.
Taste the vinaigrette to see if you want to add more honey. This is if you like a sweeter vinaigrette.
Add the cucumber, carrots, and red onions to the bowl. Toss until the salad is completely coated in the vinaigrette.
Place in the fridge for 2-3 hours or until chilled. The salad can be served immediately if time is not on your side.
You can sprinkle sesame seeds and red pepper flakes on top before serving. (optional)
