<human>:  I want to make a vegetable tart but I don't have a recipe. Could you help me with a step by step guide?
<bot>: Step 1: Preheat oven to 375 degrees. Step 2: Roll out refrigerated puff pastry on a lightly floured surface to a circle large enough to fit in a 9-inch tart pan. Place the circle in tart pan and fold the overhanging dough over the top of the pan. Step 3: Place your favorite vegetables - such as mushrooms, peppers, onion, spinach, and tomatoes - into the puff pastry. Step 4: Beat together 1/2 cup ricotta cheese, 1 egg, 1/2 teaspoon salt, and 1/4 teaspoon pepper in a bowl. Layer the cheese mixture on top of the vegetables. Step 5: Bake the tart in the preheated oven for 40 minutes, until pastry is golden brown and vegetables are tender. Step 6: Serve warm with a side of salad as desired. Enjoy!
