Peel and chop the onion and garlic.
Rinse and chop up the tomatoes.
Open the can of chickpeas, empty the chickpeas into a colander and drain the liquid out. Then rinse the chickpeas well.
Add the oil to a large pan, and turn the heat on to medium high.
Add the chopped garlic and onion and cook for about 5 minutes, stirring often so they do not burn.
Add in the chopped tomatoes, coriander, and harissa and sauté about 2 minutes.
Then add in the drained chickpeas and sauté another 3 minutes.
Turn off the pan and remove from the heat.
Season with salt and pepper to taste.
If serving with parsley, chop some up and drizzle on top and enjoy!
