Separate broccoli into bite-sized florets and blanch in boiling water with a pinch of salt.

Chop the blanched broccoli, onion, and bell peppers. Prepare the tuna and egg.

Combine chopped vegetables, tuna, egg, pancake flour, salt, and pepper in a bowl. Mix thoroughly.

Scoop the mixture onto a pan using a spoon and shape into flat, round pancakes.

Pan-fry the pancakes until golden brown on both sides.
