The tart was a big success for Joe, I really liked it and Roy loved the filling. But then again I could have told you he wouldn't like the crust and in part this is because he likes his traditional wheat based and anything beyond that doesn't get a chance (shhh, don't tell him I said that).
I filled Max's mini tart with the leek/carrot/kale combo and then added the cheese and herb topping. He LOVED it and asked was it healthy and if so could I cook it every day. Ah, any time I get 3 out of 4 I feel like my cook has not been wasted.
Check out his tart - which he let me photo:
