As I mentioned in the recipe, you can use salmon, trout, or other fish in place of the arctic char. I recommend using whatever's fresh and looks good at your fish market. See the rest of my blog post for tips on buying and cooking seafood.
I like how colorful the combination of meyer lemons and blood orange are, but you can certainly use all of one instead of both. And of course, regular lemons work fine, too.
Asparagus is one of the first veggies I crave when spring hits, but if you're not a fan you can swap them here for green beans. They cook in about the same amount of time.
If you'd like to double this recipe to serve more people, I recommend putting all of the veggies on one tray, and all of the fish on another (lay the fillets side-by-side, thick end of one next to the thin end of the other). This way if the veggies are done before the fish, or vice versa, it's easy to remove one and keep cooking the other.
