Start by cutting the beef into cubes.
In a skillet, add enough olive oil to cover the whole bottom, add all the meat cubes and let them fry until both sides are seared and all the meat juices have evaporated.
Cut the onion into small cubes and put them in the skillet, add the green chili pepper chopped into small cubes, the yellow chili pepper chopped into small cubes, the red bell pepper chopped into small cubes and stir-fry for 5 minutes.
Season with the tomato sauce, the tomato paste, the salt, the rosemary, the black pepper and the chimichurri, stir very well until incorporated.
Once you’ve done that, add the water, stir and let it all cook until it starts to boil.
Once it starts to boil, add the chickpeas. I left the chickpeas soaking in water at room temperature for 2 hours.
Cover the skillet and let it all cook over low heat for 1 hour and 20 minutes.
Serve.
