Bring a large pot of water to a boil
In a small bowl, combine the bread crumbs, cheese, oregano, salt, and pepper. Mix in 1 tablespoon of olive oil; the mixture should resemble wet sand. Set aside.
Wash the escarole well; rinse thoroughly.
Add the whole head of escarole to the boiling water and cook for 1-2 minutes, or until bright green and tender. Remove and rinse under cool water.
Chop the escarole.
In a medium, broiler-safe pan, heat the remaining tablespoon of oil over medium-high heat. Add the prosciutto, peppers, onion and garlic and cook for 4-5 minutes, or until the prosciutto is crisp and the onions are softened.
Stir in the chopped greens and half of the bread crumb mixture. Scatter the remaining bread crumbs in an even layer over the top.
Broil the Utica greens under high heat for 3-4 minutes, or until crisp and golden brown.
