For the grilled octopus, simmer the octopus in wine and enough water to cover it for about 15 minutes and let it cool in the broth for 3-4 hours.
Dismantle the octopus, use the thicker pieces. Crush garlic, salt, pepper, thyme and oregano in a mortar and mix with olive oil (about 100 ml).
Marinate the octopus with it (let it marinate for 1/2 hour). Brush grill pan with a little olive oil and brown octopus pieces nicely all around.
Brush with marinade from time to time. Prepare a dressing for the salad from wine vinegar, lemon juice, olive oil, salt, pepper and herbs and arrange the grilled octopus on the salad.
