Place chickpeas and chopped roasted red pepper in the bowl of a food processor. On a cutting board, mash garlic cloves with 1/4 teaspoon salt to a smooth paste with the side of a knife. Add garlic to food processor along with crushed red pepper, tahini, water, 4 tablespoons lemon juice, and 4 tablespoons olive oil. Process until smooth, stopping to scrape down sides as needed. Taste and adjust seasoning by adding salt, additional lemon juice, and olive oil to taste. Transfer to a wide, shallow bowl for serving.

Drizzle hummus with olive oil and garnish with parsley and paprika. Serve with pita chips.
