Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Dice the zucchini and red bell pepper into bite-sized pieces and place them on the prepared baking sheet.
Drizzle the vegetables with olive oil and sprinkle with half of the sea salt and black pepper, tossing to coat evenly.
Spread the vegetables into a single layer and roast in the oven for 10 minutes.
While vegetables roast, combine the almond meal, dried parsley, and dried dill in a small shallow bowl.
Pat the salmon fillet dry and brush the top surface evenly with the Dijon mustard.
Press the almond-herb mixture firmly onto the mustard-coated salmon to create an even crust.
Remove the baking sheet from the oven, move the vegetables to the edges, and place the salmon in the center.
Season the salmon with the remaining salt and pepper, then return the sheet to the oven.
Bake for 12 to 15 minutes until the salmon is opaque and flakes easily with a fork.
Serve the salmon and roasted vegetables immediately with a fresh squeeze of lemon juice.
