Adjust the oven rack to the middle position. Preheat the oven to 180°C. Halve and slice the tomatoes. Alternate slices of courgette and tomato in rows in an ovenproof dish.
Sprinkle with Garlic & Herb Seasoning and drizzle with olive oil. Can be prepared to this stage in advance. Keep covered in the fridge if pre-preparing. Bake open for 45 minutes until the edges of the vegetables begin to brown a little.
Pre-preparation is a good idea for this recipe. The pre-seasoning allows all the flavours to mellow, a little liquid will leak out of the vegetables which helps to steam them while baking in the oven.
