Heat about an inch of olive oil in a pan. Fry the fish pieces for a couple of minutes on each side, until they are nice and golden brown.
While you are frying the fish, place 2 cups of frozen peas into a pan with a tbsp of butter or olive oil. Once cooked through, pour into a small bowl, add mint and juice of a lemon and mix through. Season to taste.
Serve fish, chips, and peas with a side of lemon for a rustic and classic dinner.
