Chickpeas can be taken ready-made in banks. Or dry, then it should be soaked overnight, then boil for a couple of hours and only then start cooking harira.
Harira is a typical African dish that is prepared according to a simple principle: we take everything we have, cut it, throw it into a common pot and cook it until ready.
However, harira has acquired some permanent elements. Outside of Morocco, you will find everything, but inside the country, you will always find chickpeas, vermicelli and lentils, plus flour for a special structure.
But meat and eggs are optional. So you can remove them from the recipe and get a vegetarian dish.
And I will mention spices separately – they give a special flavor and are absolutely necessary.
