In a bowl, combine the sliced chicken, grated garlic, and half of the peanut satay sauce. Marinate for 30 minutes to 1 hour.
While the chicken marinates, prepare the cucumber salad by mixing cucumber, red onion, avocado oil, vinegar, salt, and sugar until evenly coated. Chill until ready to serve.
Cook the vermicelli rice noodles according to the package instructions. Drain and rinse with cold water.
Heat a lightly oiled nonstick skillet over medium heat.
Add the marinated chicken in a single layer. Let it cook undisturbed for several minutes until caramelized before turning.
Continue cooking until the chicken is golden brown and fully cooked. Sprinkle in a small pinch of sugar near the end if you prefer extra caramelization.
Arrange the cooked noodles into serving bowls.
Top with the flavorful chicken, cucumber salad, fresh herbs, and crushed peanuts.
Thin the remaining satay sauce with a splash of water, soy sauce, or chili oil until it reaches a pourable consistency.
Drizzle the sauce generously over each Thai Peanut Chicken Bowl before serving.
