Add chickpeas, mayo and avocado to a bowl. Use a fork to roughly mash everything together.
Add red onion, cilantro, curry powder, garlic salt, pepper and lemon juice to the bowl and stir to combine. Taste and adjust seasoning as needed.
Place the chickpea mixture in the fridge to cool for at least 30 minutes.
Toast bread and divide the chickpea mixture between two slices of bread. Top with arugula and the remaining slices of bread.
Cut in half and enjoy!
