Black Pepper Oat biscuits

The heavenly combination of oat biscuits, cheese and black pepper is one I would gladly eat every day. I make these in industrial quantities, omitting the black pepper from one batch for my daughter (who eats them as fast as I can make them), and keeping the pepper in the rest, for the grown-ups. You can cut them into any shape you like, and the dough is so forgiving you can roll it endlessly, so there will be no waste.
