In a pot, fry the finely chopped onion in preheated oil. Crumble 1 chicken broth cube. Add the cleaned from their skins and chopped tomatoes and 2/3 cup (150 g) corn.
Once the soup is warmed a little, transfer to a blender. Blend it and then return it back to the pot. Add the tomato salsa (mashed tomatoes), the remaining corn and stir the soup.
