Octopus salad is a light and refreshing dish that is perfect for summer. To make this salad, you will need octopus, lemon juice, olive oil, red onion, cherry tomatoes, cucumber, olives, parsley, salt, and pepper. Start by boiling the octopus until it is tender, then let it cool and chop it into bite-sized pieces. In a bowl, combine the octopus with lemon juice, olive oil, thinly sliced red onion, halved cherry tomatoes, diced cucumber, pitted olives, chopped parsley, salt, and pepper. Toss everything together until well combined. Let the salad marinate in the refrigerator for at least 1 hour to allow the flavors to develop. Serve the octopus salad chilled and enjoy the refreshing and tangy flavors.
