In a skillet set over medium heat, add ground beef and cook until browned, about 5-7 minutes. Drain excess fat and mix in soy sauce and chili flakes. Cook for another 2-3 minutes until fragrant. Remove from heat and cool slightly.

Bring a shallow dish of warm water. Soak each rice paper wrapper for 10-15 seconds until pliable. Let excess water drip off and place on damp kitchen towel.

Arrange the softened rice paper wrapper on a flat surface. Place one leaf of Thai basil at the bottom center, add a spoonful of beef mixture, and any chosen vegetables. Fold sides over and roll tightly.

Serve immediately with peanut or sweet chili sauce for dipping. Store unused rolls in an airtight container lined with damp paper towels.
