Make X shaped cuts, about 3 inches deep and 1 inch apart, all over fat side with a sharp knife.
Trim stems from spinach and cut out any course ribs.
Press the greens mixture into the cuts, packing in well with your finger to fill openings. Place the ham, fat side up, in a large, shallow baking pan. Brush it all over with part of the wine. Continue baking and brushing with the remaining honey mixture for another 30 minutes, or until the top is richly glazed. Remove the Ham from the pan and let stand about 20 minutes for easier carving.
