Who doesn't like this tasty Bistek one of the Filipinos best dish ever! It's beef sirloin cut into thinly slice pieces and tenderized it to absorb the flavor of the simple and decadent sauce you can imagine. My mom has the best bistek recipe, every time we got gatherings or family meal she never miss to serve them. I miss those old days, but i am glad that even i am thousands miles away from her, i brought her recipe with me! Last night i was craving her bistek so i managed to cook for us! Husband of course loves it and the kiddos. Flavor is really yummy that's what this recipe is all about the flavor of the sauce and how the beef so tenderly cooked plus the caramelised onions, winner!
