Mustard and tomato summer tart

Tomatoes and cherry tomatoes, spring onions, bell peppers, courgettes, radish, all sorts of salades and many others, the beautiful season of veggies (and fruit) has begun. The great thing about them is that you do not even need to cook them. If you take them organic, they are perfect as they are. At home, theses days, we eat a lot of different salades and tarts, the easier and simpler, the better. Here is one of our favourite tarts – mustard and tomato summer tart.
