It does sound like beef steak but it isn't. Bistek is one famous recipe that Filipinos cook with their eyes closed. Did I just hear someone say that I lied? Well, I'd say most Filipinos know how to cook then.
You only need the following:
1 lb of beef tenderloin, thinly sliced
5 tbsp(or more depending on your taste) of soy sauce
3 tbsp of lemon juice
2 cloves of garlic, finely chopped
1/2 tsp of ground pepper
Mix all ingredients together and marinate meat for about 15 minutes.
In a pan, fry the slices of meat. Ensure that the meat is not overcooked. Beef is always more tender if you cook it for a short while. Set aside. Save the juice that comes from the marinade and possibly from the pan when beef was fried.
In the same pan, saute coarsely chopped medium onion until translucent. Add meat and the juice to taste. Add green onions before serving.
Again, I am still catching up with Lasang Pinoy series and the truth is I had this for breakfast. No kidding! This is for you Jo, for my LP 7 entry. Is LP on its 15th now? Now I'm kidding.
