In a medium size bowl add the ricotta, Parmesan, egg yolk, lemon zest, basil, salt & pepper. Mix well.
Add the oat fibre and mix until you have a dough. If the mixture is too sticky, gradually add more oat fibre.
Take small amounts of the dough and roll into pieces, about the side of a walnut and flatten into a fritter shape. Thin will fry better.
In a shallow bowl add the remaining oat fiber and roll the fritters in the fiber to coat them.
Heat the oil in a large frying pan on a medium heat.
Place the fritters in the frying pan and cook for about 2 minutes each side, until golden. Flip them carefully, as they can be delicate.
If they fall apart, you can reshape them in the pan
Serve immediately.
