Here is my simple and delicious recipe for tomato and mustard tart, just the way we make it as a family in the summer.

This Provençal-inspired tart is as easy and quick to make as it is tasty and filling. It’s perfect as a main course for an everyday family meal. It also makes an excellent side dish, for example with grilled meat or fish.

Delicious and perfectly crispy thanks to the puff pastry, it will appeal to both kids and adults.

Enjoy, and thank you in advance for your comments!
