Preheat oven to 400°F. Prepare crust as directed on package. Place on foil-lined baking sheet. Mix rosemary, garlic powder, oregano, pepper and sea salt in small bowl. Mix cheeses and 1 teaspoon of the herb mixture until well blended.
Spread a thin layer of cheese mixture over crust to within 1 1/2 inches of edges. Arrange tomatoes over cheese. Sprinkle with remaining herb mixture. Fold about 1-inch edge of crust up over tomatoes, pleating or folding crust as needed.
Bake 20 minutes or until crust is golden. Cool 5 minutes. Cut tart into 8 wedges. Serve warm or at room temperature.
