Heat sesame oil in a large skillet and place over medium heat. Add white parts of green onions, diced red onion, and garlic and saute, stirring frequently, until the red onion begins to soften, about 5 minutes.
Add ground pork, grated ginger, water chestnuts (Skip for keto), and 1 tablespoon sriracha hot sauce or chili-garlic sauce and cook until pork is browned, broken up, and cooked through about 7-10 minutes.
Add coleslaw mix, coconut aminos or soy sauce, rice wine vinegar, white pepper, and salt, to taste, and stir until well combined. Cook, stirring regularly, until cabbage is tender, about 5 minutes.
Meanwhile, in a small bowl whisk together 1/4 cup mayonnaise and 1-2 tablespoons compliant hot sauce. Add a pinch of salt, to taste. To drizzle, place creamy chili sauce in a small plastic sandwich bag.
To plate: spoon a hearty helping of the pork-cabbage mixture in a serving bowl. Snip off the corner of the sandwich bag with the creamy chili sauce and drizzle over egg roll in a bowl recipe mixture. Garnish with green parts of the green onions and black sesame seeds.
