Add the chickpeas to a bowl and mash with a fork (keep it chunky or mash it smoother, depending on your preference).
Mix in the Greek yogurt, green onion, lemon juice, Dijon mustard, onion powder, curry powder, salt, and black pepper.
Stir until everything is well combined and creamy.
Taste and adjust seasoning (more curry, salt, or lemon if needed).
Serve on toasted bread, in a sandwich, wrap, or over a bed of greens.
