Heat a large pan over high heat. When hot, add the avocado oil. When the oil is hot, add the onions and bell peppers. Cook until softened and beginning to char, about 10 minutes. Add the garlic and ginger and a generous pinch of salt then stir to combine. Cook until fragrant, about one minute more. Transfer to a serving bowl and set aside. Do not clean the pan.

Add the ground pork to the now empty pan. Cook over high heat, stirring with a wooden spoon or spatula until it is broken up into small pieces, about 5 minutes. Add the soy sauce and sweetener and continue cooking until little liquid remains, about 5-10 minutes. Add back the vegetables and toss to combine everything. Transfer to the serving dish and garnish with peanuts and cilantro, if desired.
