In a large skillet or wok, heat the sesame oil over medium heat.
Add the minced garlic and grated ginger, sautéing for about 30 seconds until fragrant.
Stir in the coleslaw mix and bell pepper; cook for about 3-4 minutes, stirring frequently until vegetables soften.
Add the diced chicken or tofu and green onions to the skillet, tossing to combine. Cook for another 2-3 minutes until everything is heated through.
In a small bowl, whisk together the soy sauce, rice vinegar, and sriracha (if using). Pour this mixture into the skillet and stir well to coat the ingredients.
Create a small well in the center of the skillet and pour the beaten eggs into the well. Let them sit for about 30 seconds to start cooking, then scramble them into the mixture until fully cooked.
Season with salt and pepper to taste and remove from heat.
Serve hot, garnished with black sesame seeds on top.
