For the Swedish crispbread pizza, first preheat the oven to 180 degrees top and bottom heat. Spread the crispbread with tomato paste and sprinkle with grated cheese.
Cut the ham and the tomatoes into pieces and spread them with the corn on the crispbread. The tomato paste should be completely covered with topping, otherwise it may burn later in the oven.
Sprinkle the crispbread with the herbs and place in the oven for about 10 minutes until the cheese has melted.
