Freshest of fresh squid is the key. Cut tubes into 1/2″ pieces. Use tentacle heads as well.
Drizzle a cookie sheet with olive oil. Dip squid pieces in milk and then panko crumbs. Place on cookie sheet so not touching.
Preheat broiler to high. Drizzle olive oil over the squid pieces and place on top rack under the broiler for about 3 minutes, watching carefully so crumbs just get golden, not burned.
Turn for another 2-3 minutes. Tentacles may take longer again until golden brown and crunchy. Drain on paper towels.
Serve on a dish around a dip of spicy cocktail sauce.
