Drain the oil from the canned tuna and place it in a bowl. Prepare chopped onion (1/2) and carrot (1/3), and add them to the bowl along with minced garlic (1/2 tbsp), a pinch of pepper, and a pinch of salt.

Add 2/3 cup breadcrumbs and 1 egg to the mixture.

Shape the mixture into round, flat patties of your desired size.

Heat oil in a pan and fry the patties until golden brown on both sides.

Prepare the sauce by combining 5 tbsp steak sauce, 1 tbsp ketchup, 1 tbsp corn syrup, and 4 tbsp water in a pan. Simmer until thickened.
