Ingredients
Method
- Preheat the oven to 375 degrees F (190 degrees C). Fit pie pastry into a 9-inch pie dish. Poke holes in bottom of crust with a fork.
- Spread mustard evenly over bottom of crust. Cover with Swiss cheese, then arrange tomato slices over top to cover cheese in a spiral, from the outer edge to the center. Drizzle oil over tomatoes and sprinkle herbes de Provence over top.
- Bake in the preheated oven until crust is golden brown, cheese is melted, and tomatoes are curled at the edges, about 20 minutes.
