Combine all ingredients in a large mixing bowl
Mix until egg and flour are thoroughly combined with all the ingredients
Use a ¼ measuring cup to divide the mix into 6 equal cakes
Roll the ¼ cup of tuna mix in your hands to form a seamless ball
Flatten the ball, sealing any cracked edges that may appear when flattening (I flatten them just enough to ensure the cakes cook through without burning. The circle of the cake should be a little bigger than the ¼ c scoop).
Heat a flat pan or griddle on med-high heat for 2 minutes
Spray or lightly brush the griddle with oil after it has heated
Place tuna cakes on the fully heated pan and cook on each side for 3 minutes, or until golden brown with a slight charring
Eat individually or serve on a bun or in a pita
