Picadillo is a ground meat hash with vegetables. It usually has capers and green olives in it as well. This recipe may be served over rice or used as a filling for sweet peppers, tortillas, taco shells or pita breads, even spooned over toasted buns. Source of recipe: Anne Lindsay's New Light Cooking. When I made this I found the flavour of 2 tbsp of Worcestershire sauce to be too strong for my taste. I would try 1 tbsp and then taste it. I would also add the same quantity of vinegar so if you only added 1 tbsp Worcestershire sauce then only use 1 tbsp vinegar. Note: May substitute 14 oz can tomato sauce for tomato paste and water but salt content will be higher.
