How to Make It
Remove and discard giblets and necks from hens. Rinse hens under cold water; pat dry. Split hens in half lengthwise. Sprinkle hen halves with 1/4 teaspoon salt and 1/8 teaspoon pepper.
Preheat oven to 475°.
Combine artichokes and shallots in a large bowl. Toss with oil, 1/4 teaspoon salt, and 1/8 teaspoon pepper. Place shallot mixture on the rack of a broiler pan. Bake at 475° for 10 minutes, stirring once. Arrange hen halves, skin sides up, over shallot mixture. Bake at 475° for 25 minutes or until hen juices run clear. Discard skin. Place hen halves on a serving platter; cover with foil, and keep warm. Add tomatoes and olives to shallot mixture. Bake at 475° for 10 minutes or until tomatoes soften, stirring occasionally. Add tomato mixture to serving platter; drizzle with vinegar.
