Stir-fried Cabbage with Tuna

Wash the cabbage thoroughly and cut it into bite-sized pieces.

Slice the onion thinly and cut the carrot into thin slices.

Heat cooking oil in a pan and stir-fry the onion and carrot.

Add the cabbage and stir-fry over medium heat.

Drain the oil from the canned tuna and add the tuna to the pan, stir-frying together.

Season with salt and pepper to taste, then finish.
