Wash the scampi briefly, dab dry and sprinkle with lemon juice. Clean and wash the tomatoes and spring onions. Halve the tomatoes and cut the spring onions into rings. Wash lime thoroughly and cut into thin slices. Peel garlic and cut into slices. Mix scampi, tomato halves, spring onions, olives, slices of lime and garlic.
Season everything with salt and pepper and fill into two ovenproof dishes. Drizzle with olive oil and sprinkle with parmesan. Bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for about 15 minutes. Serve the scampi au gratin garnished with basil leaves. Delicious with baguette
