Preheat oven to 400f
In a large bowl mix all ingredients together until well blended - some chunks of tuna are ok.
Form into 6 even patties and place on a well sprayed baking pan.
Bake for 10-15 minutes watching for edges to turn slightly brown. Flip carefully and cook for 10-15 minutes more.
Cool completely before serving.
Store leftovers in the fridge for a few days.
Enjoy!!
