1. Preheat the oven to 400 F. Place the potatoes in a
strong plastic bag and bash with a rolling pin to crack them.
Add the oil, paprika, chili powder, cumin, sea salt, and parsley to the
bag, then shake well to mix.
2. Empty the potatoes on to a baking sheet and
spread out into a single layer. Roast for 40 minutes, shaking the tray
occasionally, until cooked through and nicely browned.
