Although there are lots of veggie burgers out there that hit the spot (if not Boca), perhaps my favorite is a walnut burger that we first tried at a local diner, Monty's Blue Plate, when we moved to Madison, and have been enjoying ever since.
After heading to this diner again and again just to eat these burgers, we learned that they're actually made by the Trempeleau Hotel in western Wisconsin, and that the hotel sells these burgers, frozen, through various outlets in Wisconsin, including our very own co-op! Since this awesome discovery, we've been buying them and cooking them ourselves at home. I recently just found that you can also buy them online, here! So, if and when we move from Madison, we won't have to despair for too long.
What would be even cooler, of course, is if we could figure out how to make these babies ourselves at home. Considering the ingredients (walnuts, cheddar cheese, mozzarella cheese, bread crumbs, organic tamari, organic eggs, canola oil, herbs and spices), my guess is that these burgers are way fattier than food we usually make, but it's totally worth it.
There are lots of walnut burger recipes out there, but I haven't found any just yet that have a list of ingredients resembling our favorite version (although there's one here, in the ninth comment, that looks similar--if anyone tries it, let me know!)
Perhaps that will be a project for the summer? Come up with a perfect walnut burger recipe? Yes!
