In a mixing bowl, combine chickpeas, avocado, green onion, cilantro, lemon juice and spices.
Smash until you get a slightly chunky mixture.
Spread a generous spoonful of the mixture on a slice of bread. Top with lettuce, sliced tomatoes and onions.
Top with the other bread slice and lightly toast before serving.
Notes
Use a fork or a potato masher to mash the chickpeas and avocado- makes it super quick and easy. You can also use your food processor if you're working with a big batch.
I chose to grill the sandwiches a bit, but you can skip grilling them if you want to.
Get creative with the toppings! I used tomatoes, lettuce and onions here, but you can also try using sliced cucumbers and bell peppers if you want to. Greens like kale or arugula can also be excellent additions to this sandwich.
