For the hummus:Place garlic in a food processor and pulse until minced. Add the beans, salt, lemon juice and tahini; pulse several times. With the motor running, slowly pour in the olive oil, stopping at 3 tablespoons to check the consistency.
Add additional oil if you prefer a thinner hummus. Continue processing until mixture is smooth.
For the chips:Preheat the oven to 375 degrees and line a jelly roll pan with parchment paper.
Cut the pita rounds into triangles and place in a large bowl. Add remaining ingredients and toss until the pita bread is well coated.
Spread in a single layer on the jelly roll pan and cook for 12-15 minutes, or until golden brown and crisp. Cool until ready to serve.
Notes
Chips will keep in an airtight container for about a week.
