Shred the cabbage. About three times with the knife 👊🏻 should do, not bad.
Then, slice 1/4 of an onion.
Stir-fry the cabbage and onion together, add the tuna (well drained of oil) and stir-fry as well.
Add one spoonful of tuna sauce and one spoonful of oyster sauce.
Crack an egg and scramble it in the pan.
Mix in 100g of rice and your fried rice is done ~~🫶🏻
