4 to 6 large onions, peeled
2 cups chopped ham
2 cups frozen, chopped broccoli, partially thawed
1 cup Italian bread crumbs
1/4 cup chopped bell pepper
1/4 cup butter, cut into chunks
1 teaspoon cayenne pepper, or to taste
1/2 cup water
Peel onions and hollow out hole in center for the stuffing. Do not make hole completely through the onion. Leave about a 1/2 inch shell at the base of the onion.
Mix together ham, broccoli, bread crumbs and bell pepper. Stuff into onion and top with a chunk of butter. Sprinkle with cayenne pepper. Place onions in crockpot. Pour 1/2 cup of water around onions, but not over them. Cook on LOW for 6 to 8 hours.
