In a blender or food processor, add chickpeas, spinach, tahini, lemon juice, olive oil, and garlic. Process for 30 seconds.

Pulse a few times, then scrape down the sides of the blender. Blend until the mixture is an even creamy texture, about 1-2 minutes. Thin with reserved chickpea liquid if needed, adding 1 tablespoon at a time.

Taste the hummus and add salt and pepper as needed, blending to combine.

In a small bowl, combine the chopped green onion tops and roasted red peppers. Gently fold half of this mixture into the prepared hummus.

Transfer the hummus to a serving bowl. Use the remaining green onion and roasted red pepper mixture for decoration on top before serving.
