Making the dressing: Warm the peanut butter in the microwave until slightly melted. This step can be skipped but makes it a bit easier to stir. Add the soy sauce, maple syrup, lime juice, rice vinegar, garlic chili paste, and ground ginger to a small bowl. Whisk together, adding water a little at a time until it reaches a smooth consistency. It should be thick but still pourable. Taste and adjust seasoning as needed - more soy sauce for salt, more lime juice for tang, more chili paste for heat, etc.
