Start by making the herb rub for the turkey breast. In a blender, combine the ground pink peppercorns, salt, thyme, parsley, garlic, and water.
Coat the turkey breast with the olive oil and pat the herb rub over the top of the turkey breast.
Cut up the apple and onion into large chunks.
In the pressure cooker, add the broth. Then add the apple and onion chunks to the bottom. Then place the frozen turkey on top of the layer of apple and onion pieces.
Cook on high pressure for 55 minutes or until internal temperature is 165° F. (Times vary cooker to cooker.)
When the turkey breast is done, remove from the pressure cooker and scrape off most of the herb rub before serving. You can optionally put the turkey under the broiler for about 3 minutes to brown the outside slightly. (Note the onion and apple act as aromatics and we didn’t serve them as part of the dish.)
While the turkey is cooking you can make the sauce.
Add all the ingredients for the cherries and cranberries sauce to a high-powered blender or food processor. Blend to combine. Refrigerate the sauce until the turkey is almost done. Then warm it up in a pot on the stove; about 2 to 3 minutes.
When the turkey is done, let it rest about 5 to 10 minutes before cutting into slices. Serve each slice with the cherry and cranberry sauce spooned over the top.
