Chop finely the onions & the bacon and fry in a pan in olive oil and some of the oil of the sundered tomatoes until soft. Add freshly grounded pepper to taste.
Pluck the thyme leaves and add to the pan.
Preheat the oven to 180° C fan.
In the meantime grease the quiche form with butter & add the ready-to-use quiche pastry. Fit the pastry into the quiche form.
Chop the sundried tomatoes, dice the feta cheese, grate the Gruyère cheese, cut the spring onions.
When the onion-bacon-mess is ready distribute it all over the quiche pastry.
Add the grated Gruyère cheese as well as the sundered tomatoes.
Mix the crème fraîche with the eggs with an egg whip until smooth, add salt & pepper to taste and pour the mess into the quiche pastry.
Distribute the baked Hokkaido slices on top and cover with the diced feta & the spring onions.
Let the quiche bake in the oven at 180° C fan for about 40 min.
