Festive Shrimp Cocktail with Cognac Sauce, Avocado, and Romaine Lettuce

Sauté the cooked shrimp in a little olive oil and garlic, then add fresh herbs, salt, pepper, and a few drops of lemon juice, then set aside.

For the sauce, mix mayonnaise, ketchup, Tabasco, Worcestershire sauce, Dijon mustard, and cognac, then season to taste with salt, pepper, and citrus juice.

Peel the avocado, cut it into wedges, and drizzle with citrus juice to keep it nice and green.
