Preheat the oven to 180C.
Brush an oven proof dish with oil. (Mine is a 26x20cm oval).
Stand a box grater in the dish and grate the courgette. Add the spinach.
In a large bowl, whisk 6 eggs with a little salt and pepper. Pour into your dish and mix with the vegetables to combine.
Cut the cherry tomatoes in half and place cut side up around the edge of the dish, on top of the egg mixture.
Top with grated cheese or dairy-free alternative (optional)
Bake in the oven for 30 minutes or until golden brown on top.
