In a large skillet, cook the 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, cook another minute. Add the tamari and sweet Thai chili sauce. Bring the mixture to a simmer and cook until the sauce coats the beef, 3-5 minutes. Stir in 2 tablespoons of chopped green onions. Remove from the heat.

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

Serve warm with extra soy, chili paste, and toasted sesame oil for dipping. To make this a dinner, serve with rice on the side.
