Ingredients:

• 1 pre-made pie crust
• 2 medium tomatoes, sliced
• 1 large onion, thinly sliced
• 1 cup shredded cheese (such as Gruyère or mozzarella)
• 1 tablespoon olive oil
• 1 teaspoon dried thyme
• Salt and pepper to taste
• 1 egg (for egg wash, optional)

Instructions:

1. Preheat the oven to 400°F (200°C).
2. In a skillet, heat olive oil over medium heat. Add the sliced onions and a pinch of salt, cooking until they are soft and caramelized, about 15-20 minutes.
3. Roll out the pie crust on a baking sheet lined with parchment paper.
4. Spread the caramelized onions evenly over the crust, leaving a 1-inch border.
5. Layer the sliced tomatoes over the onions, slightly overlapping them. Sprinkle the shredded cheese on top.
6. Season with dried thyme, salt, and pepper.
7. Fold the edges of the crust over the filling, pleating it as necessary to create a rustic look.
8. If desired, whisk the egg and brush it over the crust for a golden finish.
9. Bake for 25-30 minutes, or until the crust is golden brown and the cheese is bubbly.
10. Allow to cool slightly before slicing and serving.
