Fish In Black Bean Sauce

I'm posting the recipe here (from memory), before I completely forget about it. It's a dish that I would like to cook again since it's so easy and simple to prepare.

Fish fillet cut into small strips
black beans (tausi) - around 1 tablespoon
slivered ginger - I used plenty
chopped garlic
chopped onions
sili (optional) - just 1 pc
tokwa (optional)
1 tbsp oyster sauce

I used olive oil since I didn't have any sesame oil. I sauteed the onions, garlic, ginger and sili. Then I added the fish pieces, then the tausi. And finished it off with oyster sauce.

My dad suggested to add tofu next time. Sorry, no photo of the finished product since I everyone was hungry already.
