Drain the oil or water from the tuna cans and place the tuna in a large mixing bowl.

Finely chop the onion, chives, and parsley. Crush the garlic cloves. Add all these to the bowl with the tuna.

Place the rolled oats in a food processor and process for about 2 minutes until you achieve a fine oat flour. Add this oat flour to the bowl.

Add salt and either chili flakes or black pepper to the bowl. Mix all the ingredients thoroughly to combine.

In a small separate bowl, beat the eggs. Pour the beaten eggs into the tuna mixture. Stir everything together until well combined.

Using your hands, shape the mixture into medium-sized patties.

Heat olive oil in a skillet over medium-high heat. Once hot, add the patties to the skillet.

Cook each patty for about 3-4 minutes on each side, or until they turn golden brown.

Transfer the cooked patties to a plate lined with a paper towel to drain excess oil.

Serve the patties hot. They pair beautifully with a fresh salad, or you can tuck them into sandwich buns with your favorite toppings for a delicious burger experience.
