Increase the heat to medium-high and add the ground chicken to the skillet. Cook for about 6-8 minutes, breaking it apart with a spatula, until browned and cooked through.
Stir in the diced red bell pepper and cauliflower rice. Cook for an additional 3-4 minutes.
Mix together the soy sauce, Sriracha sauce, and sesame oil in a small bowl.
Pour this mixture over the chicken and veggie mixture in the skillet. Stir to combine and cook for another 2 minutes.
Spoon the chicken mixture into individual lettuce leaves to create wraps.
Top with sliced green onions and sesame seeds. Enjoy immediately.
Notes
Store leftovers in an airtight container in the fridge for up to 3 days. Keep lettuce leaves separate until ready to serve.
