Preheat the oven to 180°C and grease a 30- x 20-cm (base) lamington pan. Line the base and two long sides with baking paper extending paper a few centimetres above the pan to help with removing slice later.
Place barley flakes in a heatproof bowl and pour warm apple juice over barley. Leave to stand while you chop up the dried fruit and pecans.
In a large bowl mix together oats, flour, sugar, barley, dried fruit, pecans and seeds.
In a small saucepan melt margarine with honey over a low heat. Cool a little, add vanilla extract and egg and stir to combine.
Pour margarine mixture over oat mixture and mix very well. Press mixture into prepared pan and cook for 25 to 30 minutes until lightly golden. Leave in pan to cool.
These are quite nice - bit overloaded with fruit so they fell apart a bit. Will make again and use more oats and flour next time to balance out the amount of fruit. Nice with a cuppa tea. - 06 Feb 2010
