Cut the beef into bite-sized pieces.
Prepare the onion, carrot, celery, tomato, and other vegetables.
Heat a little extra virgin olive oil in a pot, then sauté the beef.
When the beef is halfway cooked, add the prepared vegetables and sauté together.
Add water and tomatoes (canned or fresh), then bring to a boil.
Season with bay leaf, salt, pepper, and other spices to taste.
Simmer on medium-low heat for 30–40 minutes until well cooked.
Serve the finished soup in a bowl.
