Breadcrumbs are important here. Panko gives a really nice texture whereas whole wheat breadcrumbs would be a good choice if you want to skip the refined grains. If you use a seasoned breadcrumb mix, reduce the amount of salt in the burgers by about 1/2.
For the salmon, you could use leftover steamed, poached, grilled, baked, whatever kinda salmon. If you don’t have any cooked salmon handy, use canned salmon! That’s what I usually do. I would recommend looking for a brand of canned salmon that is caught in the US. I really, really like Wild Planet for quality canned salmon. You can read more about their sourcing/fishing methods here.
The burgers will keep pretty well in the fridge (~3 days) or freezer (~3 months). When you’re ready to eat, pop them in a nonstick skillet to reheat because it will retain crispiness! The slaw, however, is best eaten right away. It probably has one day max in the fridge once it’s been mixed up.
Gluten Free: We tried three different GF options – almond flour, crushed Chex cereal, and GF oats. All three turned out to be great substitutes, but we liked the smooth texture and flavor of the almond flour version the best. Almond meal would work just as well too.
