Preheat oven to 375°.
Brush 1 side of bread slices with 3 teaspoons oil; place on a baking sheet and bake at 375° for 10 minutes or until lightly toasted.
Heat 1 teaspoon oil in a large nonstick skillet. Add escarole, and cook 2 to 3 minutes or until escarole wilts. Add olives and next 5 ingredients; sauté 2 minutes. Drain escarole mixture.
Top each bread slice with about 2 tablespoons escarole mixture. Serve immediately.
