How to Make It
Preheat the broiler. In a medium skillet, combine the shallots and rosemary with 2 tablespoons of the olive oil and cook over moderately low heat until the shallots soften, about 5 minutes. Add the chickpeas, water and a generous pinch each of salt and pepper. Cook over moderate heat, coarsely mashing the chickpeas, until heated through. Stir in the vinegar and keep warm.
Brush the bread slices on both sides with the remaining 2 tablespoons of olive oil. Arrange the slices on a baking sheet. Broil the bread about 4 inches from the heat for about 1 minute per side, or until the slices are golden and crisp.
Arrange the sliced soppressata and fennel wedges around the edge of a long serving platter. Spread the toasts with the warm mashed chickpeas and arrange them in the center of the platter. Drizzle the chickpea toasts with olive oil, sprinkle with pepper and serve.
