Trim any big fat pieces from the chicken. Cut the boneless skinless chicken thighs into thirds if they're large chicken thighs, and cut into half if they're smaller chicken thighs.
Put the chicken into a medium-sized bowl and mix in the salt, pepper, and cumin.
Turn the pressure cooker to Saute, and let it heat up. Add the olive oil and the onion. Saute the chopped onion until it's starting to soften, about 4-5 minutes. Turn the saute function off.
Add the cubed sweet potato to the pot. Layer the chicken pieces over the sweet potatoes. Add the remaining ingredients (except the cilantro) to the pot which includes the canned tomatoes, salt, pepper, dried oregano, minced garlic, chicken broth, sliced olives, capers, and raisins.
Set on high and pressure cook for 10 minutes. Natural release for 10 minutes before pressing the valve and opening the lid.
Add the red wine or balsamic vinegar, if desired (optional). Garnish with fresh chopped cilantro. Serve over cauliflower rice to keep the entire meal Whole30/paleo, or serve over your favorite white or brown rice. Enjoy!
