Cut the leftover roast chicken into bite sized chunks.
Roughly chop the chorizo and onion.
Heat a large, heavy-based pan and gently cook the chorizo and onion until the sausage releases its fat and onion softens.
Chop the pepper and the carrot, add these to the chorizo. Put a lid on and sweat the veggies for 5 minutes.
Add the cumin powder, stir through, then pour in the tomatoes and a drop of water. Bring to boil and simmer for 10 minutes.
Drain the chickpeas add to the stew. Add the chicken bits and cook for about 5 minutes.
Turn off the heat. Add the spinach and put the lid back on. Rest for 5 minutes, stir through the wilted spinach and taste. Season with salt and pepper if needed.
Serve warm.
