Dice the onion and fry in the butter until translucent, then squeeze the garlic. Slice the plantains, dice the tomatoes, add to the onions and fry them. Drain the corn, add and stew everything for about 5 minutes. Core the chilli pepper, cut into small pieces and add to it.
Pour in the vegetable stock, stir everything well and season well with salt, pepper and nutmeg. Finally sprinkle with freshly chopped parsley.
Danger! You can get plantains in a well-stocked Asian market.
