1. Heat coconut oil in a large skillet over medium-high heat. Season chicken with salt. Saute for about 6-8 minutes on each side. Transfer to a plate. The chicken doesn't need to be fully cooked at this point, you will return it to the heat soon.
2. Add onion to the same skillet and cook for 3 minutes. Add chicken broth, pepper, chopped cilantro and lime juice. Bring to a boil and simmer for 5 minutes.
3. Add coconut milk, bring to a boil then simmer for another 7 minutes. If the sauce still needs to be thickened, you can whisk in the starch at this point (mix 1 tablespoon starch with 2 tablespoons water, then add), bring to a boil.
4. Add chicken back to the skillet, cover and simmer for another 8-10 minutes, until the chicken is fully cooked. Enjoy!
