Ok my love I suggested the crockpot cuz turkey breast can get very dry and the crockpot helps keep that moisture if done correctly. Since you can't fit that breast in the pot you might want to slice it up and put part of the breast in the pot and make cutlets with the other part. I love doing a mini turkey feast with the stuffing (stovetop) gravy, potatoes, spinach, etc - something quicker that holiday fare.
The cutlets are easy. You can pan fry, stir fry, even bake.
