Preheat oven to 375 degrees
Brush each pita round with olive oil, then cut each into quarters and each quarter in half, to make 8 triangles. Place in a single layer on a parchment lined baking sheet (2 sheet pans for 10 servings) and sprinkle lightly with Kosher salt, and ground pepper. Bake for 8-10 minutes, turning once halfway through.
To make the hummus, add the chickpeas, lemon juice, garlic, tahini paste, half of the olive oil, cumin, and salt to a blender, and blend until smooth, scraping down sides of bowl as needed. Add water a tablespoon or two at a time to blender until hummus has lightened in color and is to the desired consistency.
Place in a shallow bowl, drizzle with remaining olive oil and ground paprika. Serve with pita chips.
