Method:
1.) To begin, slice the leeks and cook in the olive oil until soft, but not coloured
2.) Set aside to cool and preheat the oven to 165°C/gas mark 4
3.) Whisk together the eggs, cream, parsley.
4.) Stir in the cooled leeks, peas and grated cheese (leave enough cheese to sprinkle over the top of each of the tarts before baking).
5.) Divide the mixture between the tart cases and top each tart with a little cheese on top.
6.) Pop the tarts on a baking tray and bake for 20-25 minutes, or until the pastry is crisp and the tarts are golden. Best served with warm new potatoes.
7.) Enjoy!
