Halve the vanilla pod lengthways and scrape out the seeds with a knife.
Mix the quark with the maple syrup and stir in the vanilla seeds.
Finely grate the orange zest and add to the quark mixture.
Peel the orange, removing all the white pith. Separate the segments and place in a bowl.
Whisk the eggs with the milk and salt in a shallow dish. Dip the bread slices, one by one, turning to coat.
Heat 1/2 tbsp oil in a large non-stick pan. Dip 2 bread slices into the egg mixture, turning to coat both sides. Fry the slices for 1-2 minutes until golden brown then turn and cook the other side. Repeat until all the bread and egg mix are used up. Serve with quark and orange segments.
