Cook the Beef Filling: In a large skillet, cook the ground beef with black pepper over medium heat. Break up the meat as it cooks until browned, about 5 minutes. Add garlic, ginger, and chili paste. Cook for another minute. Add peanuts and tamari or soy sauce, then bring to a simmer. Cook until the sauce coats the beef, about 3-5 minutes. Stir in cabbage, basil, and green onions. Remove from heat.

Warm the Tortillas: Place one tortilla at a time in the microwave for 15 seconds to warm. Spoon the beef mixture down the center of each tortilla, then top with fresh cilantro. Fold the tortilla over the filling, then fold the sides and ends of the tortilla, rolling forward to enclose the filling. Repeat with remaining ingredients.

Make the Peanut Sauce: In a small bowl, whisk together roasted peanut oil, creamy peanut butter, rice vinegar, tamari or soy sauce, garlic, and chili flakes until smooth and well combined.

Serve: Top the rolls with sesame seeds and extra peanuts, then serve warm with the peanut sauce on the side for dipping. For a complete meal, serve with rice on the side.
