Preheat oven to 400 degrees F.
Place pita triangles on a large baking sheet and spray the surface with cooking spray. Season the tops with garlic salt. Bake 6 to 8 minutes, until golden brown and crisp.
Meanwhile, rinse and drain 1 can of the chickpeas. Place drained chickpeas in a blender and add red peppers, tahini, lemon juice, garlic, and cumin. Process until smooth. Season, to taste, with salt and black pepper. Transfer to a serving bowl and top with parsley.
Serve hummus with toasted pita triangles arranged alongside.
