Slip skins from chickpeas with your fingers.
Mash the garlic to a paste with kosher salt and pepper using a mortar and pestle (or mince and mash with a large knife) then whisk paste together with lemon juice and oil until well blended. Toss with chickpeas, then mash with a fork until mixture just holds together. Let stand at room temperature 1 hour for flavors to develop. Stir in mint. Serve with pita wedges.
Cook's Note: Chickpeas can be seasoned and mashed 1 day ahead and chilled, covered. Bring to room temperature, then stir in mint just before serving.
Preheat oven to 400 degrees F.
In a dry small heavy skillet, toast seeds over moderate heat, shaking skillet, until fragrant, about 1 minute, and cool. In an electric coffee/spice grinder, finely grind seeds and salt with paprika and in a bowl stir together with oil.
Split each pita into 2 rounds and brush rough sides with cumin oil. Cut each round into 8 wedges and arrange, rough sides up, on 2 large baking sheets. Bake wedges in upper and lower thirds of oven, switching position of sheets halfway through baking, until golden brown and crisp, about 8 minutes total. Cool pita toasts on racks. Pita toasts keep 5 days in an airtight container at room temperature.
Yield: 96 pita toasts
