Preheat the oven to 420°F and position the rack about two-thirds up (third from the top).
Place the raw chicken thighs in a 13 x 9-inch baking dish and sprinkle evenly with 1/2 teaspoon sea salt.
In a small bowl, whisk together the avocado oil, honey, lemon juice, liquid aminos (or soy sauce), rice vinegar, minced garlic, and black pepper until smooth; microwave for 20–30 seconds if the honey is too thick to combine.
Pour the marinade over the chicken and spoon it over each thigh to coat well.
Bake uncovered for 20 minutes, then check with a meat thermometer; thighs should reach 160°F internal temperature.
Remove the dish from the oven and baste the thighs by spooning the pan marinade over them.
Set the oven to high broil and return the chicken to the oven; broil 8–10 minutes until the tops are golden-brown and slightly crispy (watch closely to avoid burning).
Let the chicken rest a few minutes, then serve warm.
