Heat avocado oil in a skillet, over medium high heat.
Pat chicken thighs dry and season with salt and pepper. Add to skillet and cook for 4-5 minutes on each side, flipping only once to achieve a crispy sear and maintain moisture in the meat.
Remove the chicken from the pan, allowing to cool before slicing.
Combine nutritional yeast, peanut butter, water, tamari, apple cider vinegar, lime juice, garlic, ginger, and lemongrass in a blender on medium speed. Add oil in a steady stream to allow to emulsify.
Layer rice, chicken thighs, and vegetables into bowls.
Garnish with scallions, cilantro, cashews, and serve with dressing!
