Open a can of corn. Wash and peel the vegetables. Find a nonstick skillet, or cast iron skillet, to serve.
Finely dice the onion and sauté it over low heat in a frying pan with the addition of butter. Add the peppers and fry until soft and the liquid has evaporated.
Pour the corn without liquid into a frying pan with vegetables, drained in a colander. And fry until all the liquid evaporates in the pan. All this should be stewed over low heat, not fried. Add mayonnaise, salt to taste and half a teaspoon of sugar.
It is better to take a frying pan with a non-stick coating, or a small cast-iron one for serving, in which we fry and serve. Because at the last stage of cooking, you break or grate the mozzarella cheese into it and melt it. As soon as it melts, serve. Bon appetit.
Place oven-dried bread, different types of bread, or breadsticks next to the cheese. The appetizer is ready.
