Posting for ZWT 7. This recipe comes from mycolombianrecipes.com. The heading said "It’s popular in Colombia to cook meat or poultry in Onion or Tomato Sauce. It is the perfect weeknight meal, because it is cheap, easy, simple, fast and full of flavor. Serve it over white rice, pasta or just potatoes and vegetables on the side. This dish in particular can be made with beef or pork as well."
