Marmite is a concentrated yeast paste that helps give this burger meaty flavor - find it in the aisles of your supermarket baking aisles or in a health food store. The leftover eggplant puree can be used as a dip with toasted pita wedges. What gives it a great taste as well is the sesame or poppy seed buns! :) Cooking Light Magazine, July 2010 edition.Chilling time for grinder = 30 minutes and chilling time for the turkey = 15 minutes, not accounted for in the recipe. ;)
