From the Post Punk Kitchen Website! These were DELICIOUS! I love making my own veggie burger, and these had such a wonderfully unique taste. The salty brine of the olives mixed with the meaty texture of the mushrooms made a perfect match. One thing I also really liked about this recipe was the addition of dried tarragon. I do have a small plastic bag of the spice, but I don't really come across too many opportunities to use it. To me, tarragon has a licorice and slightly minty flavor. The flavors of dried tarragon are quite strong, but the 1/4 tsp called for in this recipe, gives the perfect subtle hint. I might be able to use up that bag after all! I did end up baking the burgers in the oven about 15 minutes longer than stated, so about 45 minutes total. I served them on toasted wheat bread with some romaine lettuce leaves and some guacamole.
