Add the olive oil, lemon juice, onion, garlic, coriander, cumin, paprika, turmeric, cinnamon, salt and pepper into a zip top plastic bag. Shake to combine. Add the turkey breast. Seal the bag and shake and massage the marinade around the turkey. Refrigerate for at least one hour, but ideally, overnight.
Transfer the turkey to your Instant Pot. Add 3/4 cup of water or poultry stock and mix to ensure everything is combined. Close the lid (following manufacture’s guide). Using the Manual setting, set the Instant Pot timer to 15 minutes on high pressure.
Once the Instant Pot cycle has completed, allow for a natural pressure release. This will take about 20 minutes. If you’re in a rush, follow the manufactures guide on how to do a quick release. Remove the lid, and remove the turkey from the pot. Allow to cool slightly, and cut into slices or chunks. For even more flavour, leave the marinade in the pot and turn the Instant Pot on to Sauté. Once the marinate is at a simmer, add the sliced/chopped turkey, and cook for 2-3 minutes.
