• 1 store-bought pie crust
• 2 tablespoons Dijon mustard
• 1 cup grated Gruyere cheese
• 3 medium tomatoes, thinly sliced (any variety)
• salt and pepper
• thinly sliced basil leaves

Roll out store bought or home made pie crust into a fluted tart pan or pie crust. Spread Dijon mustard in the bottom of the pie crust. Top with grated Gruyere cheese. Next place tomatoes in an overlapping concentric circle over the cheese. Sprinkle with salt and pepper and bake at 375 F for 40 minutes, until tomatoes look wrinkled. Sprinkle tart with basil and serve.
