Slice the chorizo into segments about the thickness of a one pound coin and add to a casserole dish. Put it on a high heat and sizzle the chorizo until it’s crisp on both sides, then add the chopped onion.
Allow the onion to soften for about 30 seconds.
Add the chickpeas (drained), chopped tomatoes and water. Bring it to a simmer, and cook for about 10 minutes to soften the chickpeas.
Add the spinach and parsley, season, and when the leaves are wilted it’s ready to serve.
