For the vegetable and cheese casserole, preheat the oven to 180° convection. Put the vegetables in the baking dish, add salt and pepper and season with chili. Finely chop the chives and parsley and mix in.
Mix Philadelphia with eggs and Gouda. Add nutmeg and season again with salt and pepper if needed. Pour the mixture over the vegetables. Bake until the crust of the vegetable-cheese casserole becomes golden (about 40 minutes).
