Use half of this recipe in the burgers and half for the grilled tomato sauce.

To julienne the vegetables, cut them into thin matchstick-size pieces using a sharp knife or a mandoline. Refrigerate them in an airtight container until ready to use, up to 3 hours.

This marinade may be made in advance and kept in the refrigerator for 2 days.
