Gordon Ramsay shows you how to make the perfect appetizer for your dinner party that is both vegetarian friendly and simple to prepare. Aubergines, or eggplants, are wonderful in this recipe which has you oven roast them with thyme, rosemary, garlic, and olive oil, then combine with coriander, lemon juice, and sour cream in a puree to be served on toasted or crackers. Amazing.
