Rinse the corn and beans in a sieve and drain. Wash the tomatoes and dice them roughly. Clean and wash spring onions, cut into rings. Mix ketchup, vinegar, salt and a few dashes of Tabasco. Mix with the prepared ingredients.
Finely crumble the chips in a freezer bag with a dough roll. Mix flour and breadcrumbs. Whisk the eggs. Turn each cheese slice first in egg, then in flour mix, again in egg and finally in the chips.
Fry the cheese in hot oil over medium heat until golden brown on each side. Serve with salad.
