Cut the flank steak in big chunks, and pour them into a big stock pot with a little of olive oil and let it sear. Make sure that every side has a nice brown.

Remove the meat and in the same pot add the onions, the red pepper, the garlic, the tomato and the worcestershire sauce. Stir for a couple minutes.

Incorporate the meat and pour the broth until it covers the meat. Let it simmer for 1 hour.

Remove the meat and shred it. Put it again into the sauce and stir for a couple minutes. Now you can serve it with the arepas.
