| 1 | Chop 150 g cooked potatoes fairly small. |  |
| 2 | Put in a bowl, salt and pepper, then add 50 g butter in small pieces. Mix well by mashing together with a fork, as coarsely or finely as you prefer. |  |
| 3 | Roll out 150 g puff or flaky pastry (pâte feuilletée) into a roughly 9-inch (22 cm) circle and lay on a sheet of cooking parchment, laid on a baking sheet. |  |
| 4 | Preheat the oven to 430°F (220°C).
Spread a layer of crushed potato on the puff pastry base. |  |
| 5 | Add a layer of spinach. |  |
| 6 | Spread the 100 g bechamel sauce on top. |  |
| 7 | And finish with 30 g grated cheese. |  |
| 8 | Bake for about 30 minutes. |  |
| 9 | Leave to cool slightly before serving. |  |
If you don't have bechamel sauce, add extra grated cheese to make up for it.
