Paksiw na Bangus Recipe

This dish is my mom's favorite dish, as she like something sour. She likes to eat this with her hands pouring a bit of patis in her rice. I also remember my grandma loves it but actually this is not my fave one. This is very easy to cook esp. if you are in a hurry and can't think of what ulam you want to serve.

Ingredients:
1 big Bangus milkfish cut into 3 portions (leave the scales on and of course remove the laman loob)
1 ginger cut into small portions (pampaalis ng lansa)
1-2 pcs. of green siling haba pangsigang
1 small ampalaya (optional)
1 small onion
Vinegar
water (just enough)
1 tsp sugar
Pepper and salt to taste

Directions:
Just put all the ingredients in a pan except for the pepper and salt, cover it and let it simmer over medium fire. Season with salt and pepper. Serve hot and it is best to eat it with patis.
