I found very good instructional blog by Susie Middleton on making of these savory tarts if you are interested in trying.

I made another wonderful recipe from her book for dinner yesterday called pan asian pork and fried rice. I loved the Southwestern taste of pork and the Southeastern Asian inspired taste of fried rice which had lots of veggies I normally do not use. Worked out really well.
