Preheat the oven to 425 degrees F. Line a baking sheet with foil or parchment paper.
Place the chickpeas on a paper towel and pat the as dry as you can. Remove any loose skins.
Put the chickpeas on a baking sheet and drizzle with olive oil or the oil of your choice. Sprinkle on the salt, pepper, paprika and garlic powder and toss well to coat. Make sure the chickpeas are in a single layer. Bake for 15 to 20 minutes, toss well and flip, then bake for about 15 to 20 minutes more.
This might make more chickpeas than you want to use - if so, keep them in a sealed container and you can reuse them! They will lose their crunchiness, but still taste delish.
To assemble the salads, slice the head of iceberg into quarters. Place each on a plate and cover it with salt and pepper. Drizzle with the avocado ranch. Sprinkle on chickpeas, radishes and chives. Serve!
