First make the Caesar's dressing. Add dressing ingredients to a blender or food procressor and blend until completely smooth. It is a thick dressing, so scrape down the sides as you go. Keep going until the dressing is smooth (If you don't have a powerful blender or food processor you need soak your cashews in water overnight to soften.)
In a large bowl, add the chickpeas and 6 tablespoons of the dressing and ¼ teaspoon salt (keep the rest of the dressing for salads, you can thin it with a little water if required).
Mash the chickpeas and dressing together, leaving some texture. Add the red onion and mix until well combined. Taste to check the seasoing and add more salt if required.
Spread each slice of bread with some dressing.
To assemble the sandwiches top bread with lettuce, then top with a layer of chickpea mash, then finish with slices of tomato.
Season the tomato slices with black pepper, then add the other slice of bread, cut in half and serve. Do this with the rest of the mixture.
Enjoy!
Notes
Add the leftover artichokes to salads, wraps or pasta salad.
You can store the mashed chickpeas in an airtight container in the fridge and any extra salad dressing in a jam jar for 3-4 days.
