In a bowl, add the chickpeas. Mash until 3/4 of the chickpeas are mashed. Add red bell pepper, green onions, sun-dried tomatoes, olives, dates, all the spices, salt, parsley, and mint, Mix well.
In another bowl, mix the tahini with lemon juice and 1 tablespoon hot water. Mix it until the tahini starts to get light and fluffy. You can add another tablespoon of water if it is getting too thick.
Once the mixture is light and fluffy, add it to the chickpea bowl and mix well. Taste and adjust salt and flavor. If the mixture is dry (depends on the chickpea brand and tahini) add in more tahini and water and mix.
You can let this mixture chill for at least an hour for the flavors to double up.
Then assemble your sandwich. Add some layers of tomatoes or crispy greens. Top with the chickpea salad and another bread and serve.
You can also use the chickpea salad in a wrap or serve it as a part of a bowl to make it gluten-free.
