Hehe, it's the traditional Caldereta recipe, I just added more than a few green chilis.
Cube a kilo of
tomatoes and boil (don't add water) for around 30 minutes in low flame. This'll be the tomato sauce.
While the tomatoes are stewing, brown about a kilo of
beef cubes in
olive oil and set aside. brown a small slab of
pork liver, chop and set aside. Brown some sliced
chorizos, and set aside.

In the same oil (or add a few more drops), sauté chopped
onions and
crushed garlic. Add the beef and the liver, and stir for a bit. Pour in the tomato sauce, and about half a cup of
white wine vinegar (this tastes better, trust me). Stew for a bit. I prefer to just partially cover the pot so the vinegar's strong taste evaporates and leaves a sweetish flavor. I don't know if that's true, but it works for me. If the sauce is too thick, just add some water.
When the meat is halfway tender, mix in some cubed
carrots and
potatoes and sliced bell peppers. Add
salt and whole
black pepper a some
laurel (or bay?) leaves. Add some whole pitted
olives too.

Stew some more until the meat is tender and that's it! Put out the flame and throw in a handful of green chilis.
I took a picture before adding the green chilis. Then completely forgot. Oops.
