Tuna Patties - cooking recipe

Ingredients

2 (5 -6 ounce) cans tuna in water, well drained (NOT oil)
1 egg
1/2 cup breadcrumbs
1/4 cup onion, cut as small as preferred
salt & pepper
oil, & butter to cook in (optional)

Preparation

Mix all ingredients.
Use more or less breadcrumbs, as needed, to soak up the moisture from the tuna and egg until it is the consistency of a \"patty\" (I'm sorry I can not explain this better!).
Make into patties 1/2 inch thick.
Sprinkle both sides of patties with pepper, and pat it inches.
Warm up oil and butter in a pan over medium heat, enough so it's hot enough to cook but not burn. You know how your own burners work.
Fry until golden brown, and flip to cook the other side.
