In a large, tall-sided skillet, heat the avocado oil over medium heat.
Once hot, add the chicken, shallot, and the white parts of the green onion. Spread into an even layer and cook, undisturbed, for 4 minutes. Stir, and cook for an additional 3 to 4 minutes, or until the chicken is totally cooked through. Strain off the excess liquid using a strainer and set aside.
To the skillet, add the toasted sesame oil and increase the heat to medium-high.
Once hot, add the garlic and ginger, sautéing until fragrant and golden, about 1 minute. Add the chicken back to the skillet and toss to combine.
Add the coconut aminos, fish sauce, rice vinegar, lime juice, sriracha, coconut sugar, salt, and red pepper flakes. Toss to combine. Cook, undisturbed, for 4 minutes until the sauce begins to caramelize.
Toss and cook for another 4 minutes, until the liquid has mostly reduced, and the chicken is a deep golden brown with crispy edges. Remove from the heat and add the sesame seeds, Thai basil, cilantro, and peanuts. Toss to combine and top with the remaining green parts of the green onions.
