Put plenty of water in a small sauce pan (about two or three times as much as the mixed grain) and add the millet. Bring to a boil over medium heat and reduce the heat to low. Cook for about 5 minutes and then strain in a colander.
Soak the diced aubergine in water to remove its bitterness. Strain well in a colander and fry in a frying pan over a medium heat. Add the ingredients and turn off the heat. Leave to cool.
Cut the vegetables into 7 to 8 mm cubes (reserve some for garnishing) and put them into a storage container with the millet from Step 1 and the aubergine from Step 2, as well as the sweet corn.
Add the seasonings to Step 3 and mix well. Chill in the fridge. Place a cake ring on a serving plate and spoon the salad mixture. Press gently.
