Wash cabbage, kale and onions with cold water. Chop or shred cabbage, kale, and onions and place in a large bowl. Add red and black pepper. Mix all ingredients thoroughly.
Prepare ham for stuffing by making 1 or 2-inch slits all over the ham, about 1- to 2-inches deep. Using your gloved hand, press stuffing into slits until full. Fill large cavity where bone was located with stuffing also.
When finished stuffing, tie ham with string. Wrap ham with cheesecloth and tie securely. Cover ham with aluminum foil and bake for 5 hours.
When ham is finished, drain and let ham cool down overnight in the refrigerator before carving. Serve cold.
