Tarte of Tomatoes and Whole Grain Mustard

Again, less of a recipe than a good idea, deliciously executed by the Bessieres with some of the last of the fresh tomatoes:

Prepare a pate brisee, or pasty base of your choice.

Roll into an thin oblong or to fit a baking sheet. Spread a fine layer of whole grain mustard over the entire base, then a layer of thinly sliced tomatoes.

It was also delicious with green tomatoes, stolen from Mamielette's horde for making confiture.
