Preheat your oven to 400°F (200°C). Spread the drained chickpeas evenly on a baking sheet and toss with cumin, paprika, and a tablespoon of olive oil until well coated.
Roast the chickpeas in the oven for about 20 minutes, shaking the pan halfway through, until they are golden brown and crunchy.
While the chickpeas cool slightly, slice the cucumbers into thin half-moons and place them in a large mixing bowl.
Add the cooled roasted chickpeas to the cucumbers in the bowl, gently tossing to combine the textures.
Pour the ranch dressing over the mixture and toss again until everything is evenly coated, allowing the flavors to meld for a few minutes.
Serve the salad immediately, showcasing the vibrant contrast of crunchy chickpeas, crisp cucumbers, and creamy ranch coating.
