Beef Bok Choy with Pho Noodles

I discovered an easy economical 30 minute Vietnamese dish using a P60 package of Filipino beef tapa. First you have to purchase 2 strands of Tagalog Pechay costing P15 pesos and a P60 package of Pho rice noodles at your favorite Oriental store. Here's the recipe:

Ingredients:
  1 lb. of beef tapa sliced
  1/4 k or 1/2 package of Pho noodles
  2 tblspns. flour
  2 trands of bok choy (Tagalog pechay), sliced 1 inch long
  2-3 tblspns. oyster sauce
  1 tblspn. sesame oil
  2 tblespns. crushed dried hot peppers
  3 cloves of garlic, diced
  1/3 cup white wine
  dash of black pepper

Instructions:
Boil noodles for 3 to 4 minutes and set aside in a bowl. Mix the sliced beef with flour, hot peppers, garlic. Heat pan and pour 1/4 cup cooking oil and sesame oil and saute the beef for 2 minutes adding the oyster sauce. Add the white wine and stir until sauce thickens, then add the bok choy.  Continue stirring for about 2 minutes then add the black pepper. Pour the mixture over the noodles and serve while hot. Enjoy!
