Preheat the oven to 180c/350f.
Line a large dish with baking paper (we use a 10”x10” dish), then add all of your chopped veggies gently mixing to evenly distribute them. Add all of the remaining ingredients (not the cheese or carrot) to a jug or bowl and mix together with a fork to remove any lumps.
Pour the chickpea flour batter over the veggies and gently mix together with a fork.
Top with the carrot and cheese and then place in the preheated oven and cook for 40-45 minutes until a skewer comes out clean. It will continue to firm up as it cools.
Remove from the oven dish after 10 minutes, and then gently remove the baking paper once cooled.
