In a good processor, combine the chick peas, tahini paste, olive oil, lemon juice, minced garlic, salt and pepper. Pulse until it reaches your desired consistency. The longer you blend it, the creamier the mixture will be.
Pour mixture into a dish and top with a drizzle of olive oil and some crushed red pepper, if desired. Set aside.
To make the tortilla chips, preheat oven to 350°F.
Cut each tortilla shell into six wedges. Place onto prepared baking sheets and lightly brush both sides with olive oil. Sprinkle garlic powder, Parmesan cheese, and sea salt over chips (flip over if you would like both sides coated).
Bake for 12-15 minutes or until chips are crispy and golden. Remove from oven and let cool for 5 minutes.
