Tomatoes on the plate or Tomatoes with breadcrumbs

My grandmother used to make this dish, followed by my mother. Now, I make it too and it is one of our favorites. You can also find it in the book "Σαρακοστιανά". It is one of the foods of the "poor cuisine", since they used to make it with whatever was available in the house, a bit of stale bread, some tomatoes from the garden, an onion or two, some garlic... But the result is great.
