pork Steak and onion sauce

Malaysians(non muslims la) are partial to pork. In fact, we make pork perattal instead of beef perattal. we have pork ball mee for break fast, pork curry in different versions for lunch and again, noodles with pork for dinner.
This particular recipe is my favourite. It is very unique


Pork fillet:4


Onion: 1 chopped
garlic:2 cloves
tomato sauce:3 tbl spn
soy sauce:3 tbl spn
brown sugar:1 1/2 tbl spn
Chilli powder:1 t spn

Blend all of the above( not the pork). Heat a tbl spn oil and cook the blended ingredients for 10 mints, till it is nice and thick. Cool, marinate the pork fillet in this mix for 5 hours.( keep refrigerated)..stirring every now and then.
Grill, bbq, or broil.

The remaining sauce is again cooked in a pan for another 10 mints and pour over the cooked steak.
