Preheat the oven to 400°F (200°C).
Spread the chickpeas on a baking sheet and drizzle with 1 tbsp of olive oil.
Sprinkle with cumin, coriander, paprika, salt, and pepper, then toss to coat evenly.
Add the chopped pitta to the baking sheet, drizzle with ½ tbsp olive oil, and mix together.
Bake for 25–30 minutes, stirring halfway, until the chickpeas are crisp and the pitta is golden brown.
Squeeze lemon juice over the mixture and toss with parsley.
Serve warm with a dollop of yogurt, if using.
