  • Drain thoroughly.
  • Wrap in a towel, and squeeze to remove excess moisture.
  • Unwrap, chop finely, and set aside.
  • Place the cherry tomatoes in a small bowl.

  • Saute about 3 minutes.
  • Stir in cherry tomatoes and remove from heat.

  • With the remaining 1 tablespoon olive oil, grease a shallow 10-inch round baking dish or pie plate.
  • Dust the bottom with 2 tablespoons of the bread crumbs.
