new garlic and mushroom tarts

On this, what has to be, the hottest day of the year I decide I'm having a barbecue.   I'm very much a Johnny come lately to the barbecue as I've never lived anywhere in my adult life before with the outside space to have one.  When we moved last year to a house with a lovely big garden and patio I put that right, buying a cobined pizza oven/BBQ.  I've not quite mastered pizzas in it though, preferring the barbecue rack.  My vegetarian boyf is obviously not impressed or enthused by a barbie so I made these tarts for him alone for when I'm gnawing on a bone.  I was really pleased that when I handed the plate to him he said in a really impressed sound way 'have you made these?' and he very much seemed to enjoy them, wolfing down two quick smart.
