Preheat your oven to 400°F (200°C). In a mixing bowl, combine the drained, rinsed, and dried chickpeas with 3 tablespoons of olive oil. Add the ground chili powder, ground cumin, paprika, onion powder, garlic powder, dried oregano, salt, and pepper. Toss everything together until the chickpeas are well-coated with the oil and spices.
Spread the seasoned chickpeas evenly on a baking sheet. Roast in the preheated oven for about 25-30 minutes or until they are golden brown and crispy, shaking the pan halfway through for even cooking.
While the chickpeas are roasting, prepare the dressing. In a small bowl, whisk together the sour cream, 2 tablespoons of olive oil, honey, minced garlic clove, chopped jalapeño, and the juice of one lime. Adjust the seasoning with salt and pepper to taste.
Once the chickpeas are done roasting, remove them from the oven and let them cool slightly. In a large bowl, combine the cooked quinoa, roasted chickpeas, and chopped cilantro. Squeeze the juice of the remaining lime over the mixture and toss gently to combine.
To serve, spoon the chickpea and quinoa mixture onto plates, drizzle with the prepared dressing, and top with sliced avocado. Enjoy your vibrant and flavorful Mexican Chickpeas!
