Gather all the ingredients for your chicken lettuce wraps.
Heat the olive oil in a skillet over medium heat. Sauté the white part of the green onions, ginger, garlic, and serrano pepper for 2 minutes or until soft.
Add the chicken to the skillet and cook for 3 to 4 minutes, breaking up any clumps with a spatula.
Meanwhile, whisk together peanut butter, soy sauce, honey, sesame oil, and water to make the peanut sauce.
Pour the peanut sauce into the skillet and cook for 3 minutes, stirring occasionally, until it thickens. Remove from heat.
Stir in the green part of the green onions and jicama until everything is evenly coated with the sauce.
Assemble the lettuce wraps by layering the brown rice and seasoned chicken mixture onto two crisp butter lettuce leaves for each wrap.
Top the wraps with cucumber slices and chopped parsley.
Serve with a squeeze of lime juice and enjoy!
