I really enjoyed looking through the June issue - and I flagged a lot of things that happened to be GF, or could be with minimal effort.
These salmon burgers are GF as long as you leave off the bun. It was easy to whip up in the food processor. We liked them pretty well but did not think it was particularly exciting. I might increase the cilantro and green onions in the future.
In addition to the items mentioned, I also topped mine with avocado which I thought was a great addition.
