In a large skillet, cook the ground beef with black pepper over medium heat, breaking up the meat as it cooks until browned, about 5 minutes. Add the garlic, ginger, and Chinese 5 spice, and cook for another minute. Pour in the tamari and Thai chili sauce, bringing the mixture to a simmer and cooking until the sauce coats the beef, approximately 3-5 minutes. Stir in 2 tablespoons of chopped green onions and remove from heat.

Place one tortilla at a time in the microwave for 15 seconds. Spoon the cooked beef mixture down the center of the tortilla, then top with cucumber, cilantro, basil, green onion, and peanuts. Fold the tortilla over the filling and then fold the sides and ends to encase the filling, rolling forward. Repeat with the remaining tortillas and filling.

Serve the rolls warm with extra soy sauce, chili paste, and toasted sesame oil for dipping. For a complete meal, consider adding rice on the side.
