Simple sauteed green beans, mushrooms and onions has to be one of my favourite side dishes but it is always nice to change things up and to use that fabulous combo in other dishes! I recently came across the idea of using the combo in a green bean and mushroom tart on A Spicy Persective and of course I just had to try it. I have been enjoying the ease and simplicity of puff pastry tarts for a while now and you really cannot get much easier that rolling out some puff pastry, topping it with your favourite toppings and baking it for a few minutes in the oven! For this particular tart we are topping it with blanched green beans and caramelized mushrooms and onions. Of course it is always nice to have something on your tart to hep the other ingredients stick to it as you eat and some blue cheese works wonderfully well with green beans and mushrooms on this tart!
