As for the preparation of spaghetti with garlic, oil and chilli pepper, put these ingredients on the stove and when the garlic is golden brown, add the tomato puree.

Season with salt and pepper and after the tomato has seasoned add the chopped bread as finely as possible.
Add some vegetable broth or even just water, remembering to adjust with salt.
Boil abundantly for an hour trying to be careful of the bread that sticks to the bottom of the pan.
When the bread has amalgamated and become creamy, serve on the table and let it cool a little.
