Vegetable Tian is a dish that can be made easily and quickly.
It originates from the Provencal area of France and contains fresh summer vegetables which are to be found there in abundance.
Vegetable Tian A Fabulous Summer Dish
The name Tian refers to the dish that it is cooked in (which is an
earthenware vessel of Provence according to Wikipedia) but nowadays you
here the word being used for lots of Mediterranean dishes.
If you don't have a Tian dish just use any dish you have that is ovenproof.
If you are on holiday in France where you will have access to the wonderful vegetable markets, this is one way of using the fresh produce.
Of course you can make it wherever you are just as I do and bring a little Provence right there to your kitchen!
