In a large skillet over medium heat, heat oil. Add ginger and garlic and cook until fragrant, 2 minutes. Add ground pork and cook until no longer pink, 5 minutes. Add hoisin sauce and Sriracha and stir until combined.
Spoon pork into lettuce leaves and sprinkle with carrots, scallions, and sesame seeds and drizzle with Sriracha. Serve with extra hoisin, if desired.
