Prep: Preheat oven to 400°F (204°C). Pat dry chickpeas with paper towel, removing any skins that may come off. Gently toss chickpeas with oil, paprika, black pepper, cayenne pepper, and salt.
Roast: Spread chickpeas onto a greased rimmed baking sheet and roast for about 20 minutes, until lightly browned but not hard.
Assemble: Spread some tzatziki onto one side of the pita, then sprinkle in ¼ of the chickpeas and add veggies. Fold in half and enjoy!
