  • 1/2 of a 17.3-ounce package Puff Pastry Sheets (1 sheet), thawed
  • 2 tablespoons butter
  • 8 ounces portobello mushroom, cut into 1/2-inch slices
  • 3 tablespoons chopped fresh basil leaves

  • 2 medium tomato, thinly sliced and cut in half


  1. Heat the oven to 400°F.

  2. Unfold the pastry sheet on a lightly floured surface.  Cut the pastry sheet into 3 strips along the fold marks. Cut each strip into 6 rectangles, making 18 in all. Place the pastry rectangles onto a baking sheet.

  4. Heat the butter in a 10-inch skillet over medium heat.  Add the mushrooms and cook until tender and the liquid is evaporated. Stir in the basil.
