Into a large mixing bowl add the flour, diced venison, salt and black pepper, then mix well.
Place a large saucepan on a medium heat and add the vegetable oil. When the oil is hot add the floured venison and brown well on all sides.

Finally add the frozen peas and frozen sweetcorn, remove the saucepan from the heat and allow it to stand for 15 minutes.
