Place chickpeas in a food processor and pulse a few times to get a rough chop.
In a large bowl, combine chickpeas and all remaining ingredients and mix well. Add salt and pepper to taste. Chill in the fridge for one hour to let flavors combine.
When ready to serve, toast the bread to your desired darkness in a toaster oven, or under the broiler (watching carefully)! Divide your chickpea salad between 4 slices of toast and top with lettuce, if desired, and the remaining toast. Or suit yourself and eat open faced, or on a bed of lettuce. Enjoy!
