In a mixing bowl, combine Orange Marmalade and can of Whole Berry Cranberry Sauce together.
Pour a small amount of the sauce into the bottom of a crock-pot or slow cooker. Place thawed boneless turkey breast into the slow cooker. Pour remaining orange-cranberry sauce over the top of your turkey.
Preferrably, cook on low 8 hrs for most tender meat. Or on high 4-5 hours.
This recipe is easily doubled for a large crockpot and bigger serving! Enjoy!
