Defrost frozen salmon. Mix quark, oil, 1 egg yolk, 4 tablespoons milk, 1/2 teaspoon salt and 1 pinch sugar. Mix 200 g flour and baking powder. Stir in half, knead in the rest with the dough hooks of the hand mixer.
Wash and halve the tomatoes. Clean, wash and cut the sugar snap peas into pieces. Wash salmon, dab dry and dice. Wash dill and chop finely. Whisk with 3 eggs and 1/8 l milk.
Season with salt and pepper.
Grease a tart mould (24 cm Ø). Roll out the dough onto some flour (approx. 28 cm Ø) and press it into the tin. Spread salmon and vegetables on top. Pour egg milk over it. Bake in a preheated oven (electric cooker: 200°C/circulating air: 175°C/gas: see
oven manufacturer) on the lower rack for 30-40 minutes until golden brown.
