I don't particularly like chickpeas, or many legumes to be honest, and I think it's mainly because of the texture. I do not like mush (overcooked beans and peas, bananas, weetbix) and to me, legumes = mush.
Mark Bittman really sold this recipe to me on the basis that it would be crispy more than mushy - and he was telling the truth!
The concept is simple, as it is in most Bittman recipes, fry chickpeas, add chorizo and fry some more then remove from the pan. Cook the spinach down with some sherry then thrown the chickpea/chorizo mix back in, toss together and serve.
