Mix the flour, ground flaxseed and salt and knead the butter well.
Mix in the chopped pumpkin seeds and add enough water to make a soft shortcrust pastry.
Butter a 30cm quiche pan and sprinkle with breadcrumbs.
Spread the dough piece by piece in the mold and press it flat, pulling up the edge.
Now place in the refrigerator for an hour and let cool down.
Prepare the base:
The pumpkin flesh is rubbed over the coarse grater, the leek cut into fine rings and the bell pepper, depending on the type, in strips or rings.
Mix the vegetables well in a large bowl and set aside.
Making the cast:
Put the creme fraiche in a bowl and fill the beaker with milk, add this to the creme fraiche.
Add all other ingredients for the glaze, mix well and season very strongly. It can be a little over-seasoned, because the topping will season the entire topping.
Bake quiche:
Remove the chilled base from the refrigerator and distribute the vegetables evenly on top. Press something on and pour the glaze over it.
Slide the quiche onto the second rack from the bottom of the preheated oven and bake at 180 ° top / bottom heat for 20 minutes.
Take the quiche out briefly and spread the cheddar on top. Bake for another 25-30 minutes.
