Preheat oven to 350 degrees Fahrenheit .
Combine the soy sauce, sweet chili sauce, and peanut butter in a small saucepan over low heat. Whisk together until combined. Add the lime juice and stir together. The sauce should have the consistency of a cake batter. If the sauce is too thin, cook a little longer. If the sauce is too thick, add one tablespoon at a time of water.
Pour the sauce over the chicken thighs and marinate for a few hours in the refrigerator.**Note – if you like extra sauce, double the peanut sauce recipe, pour half the sauce over the chicken and the other half into a small bowl, and refrigerate. In a 350-degree oven, Place chicken onto a sheet pan and bake for 30-40 minutes or until chicken is fully cooked and nicely browned.
Top the chicken with green onions, chopped cilantro, and crushed peanuts.
Serve immediately.
