I have found most recipes use breadcrumbs as the filler..i prefer mashed potatoes - the taste this way is great. Also note that you can really add whatever tickles your fancy to the mixture - coriander and curry - corn and cilantro - these tuna cakes are so versatile!
Ingredients:
2 cans tuna fish
1/2 cup onion, chopped very finely ( you can also cook the onions before adding to the mixture)
2 medium potatoes, boiled and mashed
Fresh parsley, chopped
Garlic, crushed (use as much or as little as you like)
1 egg, beaten well
Salt and Pepper
Flour or breadcrumbs to roll in.
peanut oil for cooking.
Method:
Mix all the above!!
Shape into patties.
Roll in flour or breadcrumbs
Fry, turning until both sides are nice and brown.
You could also grill these patties - but i like frying them in peanut oil..nice and light!
