Wash, clean and dice the vegetables. Peel onion and garlic. Chop the onions finely. Press garlic through a garlic press. Roast 40 g pine nuts in a pan without fat. Wash thyme, shake dry and chop leaves coarsely.
Heat the oil in a pot. Fry the aubergine and courgette for about 5 minutes while turning. Add onion and garlic and fry for another 3-4 minutes. Add tomatoes and roasted pine nuts, season with salt and pepper and place in a bowl.
Stir in the ricotta and thyme.
Grate parmesan. Bring the cream to the boil and stir in 80 g parmesan. Season to taste with salt and pepper. Put some Parmesan cream in an ovenproof dish (approx. 12 x 25 cm). Fill the cannelloni with the vegetables and place them in 2 layers in the baking dish.
Pour parmesan cream over it. Sprinkle the remaining Parmesan and pine nuts over it and bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 20 minutes.
