In a food processor or blender, puree the avocados, chickpeas, garlic, tahini paste, lime juice, olive oil, cumin, and salt and pepper.
If you like a thinner consistency, add more olive oil.
Spoon into a bowl with a drizzle of olive oil, and chopped parsley and a little black pepper on top.
Preheat oven to 400°F.
Cut pitas into small triangles.
Season with olive oil, cayenne, garlic powder, and salt and pepper.

Serve with the hummus!
