In a skillet over medium heat, add the ground beef and cook until browned, about 5-7 minutes.

Drain excess fat, then add garlic, ginger, bell pepper, soy sauce, hoisin sauce, sesame oil, and red pepper flakes. Stir to combine.

Cook for an additional 5 minutes until the vegetables are tender.

Stir in green onions just before removing from heat.

Take a lettuce leaf and spoon a portion of the beef filling into the center.

Top with shredded carrots, sliced cucumber, and fresh cilantro.

Wrap the lettuce around the filling and enjoy!
