Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Slice the red bell pepper into thin strips and place them on the baking sheet with the broccoli florets.
Drizzle the vegetables with 1 tsp of olive oil and season with half of the sea salt and black pepper.
Toss to coat evenly and roast the vegetables in the oven for 10 minutes.
While the vegetables roast, pat the salmon fillet dry with a paper towel and brush the top surface with Dijon mustard.
In a small bowl, whisk together the almond flour, dried parsley, garlic powder, and the remaining salt and pepper.
Press the almond flour mixture firmly onto the mustard-coated salmon to create an even crust.
Remove the baking sheet from the oven, move the vegetables to one side, and place the salmon on the other side.
Drizzle the remaining 1 tsp of olive oil over the herb crust on the salmon.
Return the pan to the oven and bake for 10 to 12 minutes until the salmon is opaque and flakes easily with a fork.
Serve the salmon and roasted vegetables immediately with a fresh lemon wedge for squeezing.
