I found this wonderful recipe for Focaccia in the back of my cupboard a few weeks ago...
Lightly greese a 33X23 cm (13"X9") baking pan with cooking spray. Unroll pizza dough and press evenly over the bottom and about 2.5 cm (1") up the sides of the prepared pan. Brush dough with olive oil;sprinkle with garlic and basil. Cover with tomatoes, artichoke hearts and mushrooms. Sprinkle with Feta cheese and green pepper. Bake at 220 °C (425F) for about 20 minutes or until crust is golden brown. Makes 8 servings.
