Turkey Burgers (originally from Comestible Zone)
Sounds pretty good.
As always, substitute something for the salt. Personally, I'd add some worcestershire to the turkey--but a very, very small amount, maybe 1/4 tsp. for the whole thing. I play around with seasonings so you might well want to do the same. I also love fried onions on burgers and if you want to kick it up a notch, you could caramelize the onions and put over the burger. Num num. Caramelizing onions. You can try it without any salt; however, I'd probably use just a tiny pinch since the salt draws the moisture out of the onions and they may not caramelize right without at least a tiny bit of salt. Give it a try.
