Approximate cost/serving: This depends on the cost of your salmon. While farm raised salmon is going to be cheapest, we prefer sustainable, wild caught Alaskan salmon. The best way to make this affordable is to buy whole salmon and fillet it yourself. It's surprisingly easy! When we found a whole salmon for just $8/lb, this cost us less than $3 a serving. That's crazy!
Gluten Free: Yes completely! This can also be dairy free and paleo by making your own pesto with no parmesan.
