Place chickpeas in a large bowl and add water. Allow the chickpeas to soak overnight. Make sure chickpeas are fully covered by the water.
Pour the chickpeas and the water they soaked in into a pot and bring to a boil. Once boiling, reduce the heat to low, partially cover and allow to simmer until very tender. Skim any foam that may develop at the surface.
Once the chickpeas are fully cooked, add the salt, pepper, and cumin. Stir and remove from heat.
Serve hot in a bowl and add your preferred garnish. You can go simple and traditional with just pepper flakes and a drizzle of olive oil. Or go all out and add the stale bread to soak up the broth, a generous spoonful of harissa, some good quality Tunisian tuna, and a poached egg to top it all off.
