Preheat oven to 350 degrees.

Place 1 tablespoon of olive oil in the bottom of a 9 x 13 inch baking dish. Sprinkle a teaspoon of chopped garlic over the oil. Place the escarole in the baking dish. Sprinkle the remaining garlic over the escarole. Place a layer of the anchovy fillets over the escarole. Open the anchovies, so the flesh is on the escarole and the skin side is up. Sprinkle salt, pepper, red chili flakes and olive oil over the anchovies. Tightly cover the baking dish with aluminum foil. Transfer into the oven and bake for about 15 to 20 minutes until the greens are tender and the anchovies have softened.

Transfer out of the oven and serve hot.
