Hearty bread soup

This is a Portuguese inspired, hearty, bread soup. I used left over baguette from a day ago but you could use similar stale, crusty bread (not sourdough). I also served it with homemade piri-piri sauce for extra zing!

Ingredients:
1/2 baguette, torn into large pieces
a handful of rocket or arugula
4-5 garlic cloves, smashed
4 cups chicken or vege. stock
salt
black pepper
1 tbsp olive oil
1/2 red onion, sliced
1 bay leaf
1 sprig fresh or dried rosemary

Method:
Saute the onion, bay leaf and garlic in hot oil until softened. Add the stock, bread, rosemary and simmer. Season with salt and pepper to taste. The bread should soften in a few minutes...you can additional water if needed. Now, add the rocket and stir until wilted.
Turn off heat, ladle into bowls and top with some piri-piri.
