Preheat oven to 180°C (160°C fan-forced).
To prepare the rhubarb cut it into 10cm lengths. Place in a shallow roasting pan.
In a small saucepan combine sugar, orange juice & ginger together over a medium heat, stirring until sugar has dissolved.
Pour mixture over the rhubarb, cover with foil & cook in preheated oven for 15 minutes. Remove foil & cook for a further 15 minutes or until rhubarb is tender, but still holding its shape.
Remove from oven & set aside to cool to room temperature.
For the French toast whisk the eggs & milk together in a bowl until well combined & on a separate plate combine sugar & cinnamon together for later.
Heat a large non-stick frying pan over a medium heat & melt a little of the butter.
Dip two slices of bread at a time into the egg mixture, place in pan & fry for 1–2 minutes
on each side, until golden.
Remove the French toast from the pan & dip on both sides in the cinnamon sugar. Repeat with the remaining slices of bread.
Serve two slices of French toast topped with slow roasted rhubarb & a dollop of vanilla yoghurt per person.
