Tomato, arugula and grana padano tart and a Sunday miracle

A miracle happened in my house last Sunday – I said I was going to make this tart for lunch and Joao said he was going to eat it, too. :D
After lunch, he said the tart was delicious, which made me both surprised and happy – those of you with picky eaters at home know the feeling... :)

It’s a very simple recipe, with almost no cooking involved, but I had to share it with you.
