1. Preheat the oven to 200°C. Use the pastry to line a square or round 23cm fluted loose-based tart tin, trimming off the excess. Bake until light golden, following packet directions. Remove and set aside.
2. Meanwhile, heat a large non-stick frying pan over medium-high heat. Crumble in the sausage meat, add the onion and cook, stirring often, for 6 minutes or until the sausage meat is browned.
3. Spoon the sausage mixture into the pastry-lined tin, spreading it to the edges. Arrange the pear slices on top and sprinkle with the gruyere.
4. Bake the tart for 25 minutes, until the cheese has melted, pears are tender and pastry is golden.
