Heat a little oil in a non-stick frying pan. Beat the eggs in a shallow dish. Dip the slices of raisin bread in the egg, turning until coated, then add to the hot oil pan. Cook 2-3 slices at a time, for 4-5mins, turning over once until they are golden on both sides. Transfer to a plate and keep warm. Repeat with the remaining egg and bread.
To serve, cut the eggy bread slices in half and arrange three pieces per person. Scatter over a few raspberries and blueberries and serve with crème fraiche.
