You can make a different cafe salad every day - from eggs, potatoes and tuna, or chicken, beans and tomato, or asparagus, avocado and ham - you get the idea.
Heat the oven to 200°C/Gas 6. Cut the tomatoes in half and arrange on a baking tray. Season with sea salt and pepper, drizzle with 1 tbsp olive oil and bake for 20 minutes
