In a large mixing bowl, combine the drained canned tuna, breadcrumbs, shredded cheddar cheese, mayonnaise, egg, and seasonings. Mix until just combined.

Shape the mixture into patties, roughly the size of your palm, and chill in the refrigerator for 15–20 minutes.

Heat a non-stick skillet over medium heat with a drizzle of cooking oil.

Add the patties to the hot skillet in batches, cooking each for 4–5 minutes on each side until golden-brown.

For extra cheesiness, sprinkle some cheddar on top during the last minute of cooking and cover with a lid.

Serve immediately while warm, alongside bread or salad, or on their own.
