I love tuna flakes, I think they're the most versatile food ever. You can put it in soups, in stir-fries and any dish with fish to add flavor and texture. It tastes great!
The other day, I made fish cakes with it. I basically just mixed the tuna flakes with some mashed potatoes and spices. Then I just put it on a baking sheet and cooked it in the oven. It came out nice and crispy on the outside and soft on the inside. It was delicious and it was as if I used fresh fish.
For most una flakes recipes, I used canned tuna flakes, but for soups, I use dried tuna flakes that are sold in the bag. It's sort of like bacon bits.
