Preheat the oven to 180° C. Unroll the pastry and line a 22 cm round quiche tin with the pastry. Lightly prick the base and refrigerate to keep cool.
Whisk together the eggs, cream and milk. Season with salt and pepper. Set aside.
Top the lined quiche with cherry tomatoes and grated cheese, pour over the egg filling and top with a sprig of thyme, bake in the preheated oven for 30 – 40 minutes, until the quiche is set and pastry cooked through.
