Ukrainian Daughter's Slow Cooker Casserole

"A Ukrainian recipe for slow cooker casserole- a huge Ukrainian meal in one pot, including kielbasa sausage, cabbage, rice and pierogi/perogy flavors. Prepped in 20 minutes - the slow cooker does the cooking for you! On the heels of our wonderful Malanka (Ukrainian New Yearscelebration), with 11 long months to go until the next Malanka, I wanted to drown our collective sorrows and capture a little of the spirit of that night with my Ukrainian Daughter’s Slow Cooker Casserole. This slow cooker casserole is a giant Ukrainian feast in one pot!"
