It's a family recipe from my Canadian cousin Lynda who's one terrific cook. I've made it sooo many times ... with wild salmon from my favorite St Louis fishmonger Bob's Seafood, with salmon steaks from Trader Joe's, and then as shown here for a small crowd, with a big slab of salmon from Sam's or Costco. All are delicious!
And if you like the looks of the lemony zucchini, they're roasted at the same oven temperature (500F!) and pair beautifully with salmon ... so do feta-stuffed zucchini boats and summer lentils.
