Grilled octopus is a popular dish in many Mediterranean cuisines. To make this delicious recipe, you will need the following ingredients: octopus, olive oil, lemon juice, garlic, salt, and pepper. Start by cleaning the octopus thoroughly and removing its beak. Then, bring a large pot of water to a boil and blanch the octopus for a few minutes to tenderize it. After blanching, remove the octopus from the pot and let it cool. Once cooled, marinate the octopus in a mixture of olive oil, lemon juice, minced garlic, salt, and pepper for at least an hour. Preheat your grill to medium-high heat and grill the octopus for about 3-4 minutes per side, until it is nicely charred and cooked through. Serve the grilled octopus with a drizzle of olive oil and a squeeze of lemon juice. Enjoy this tender and flavorful seafood dish!
