Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
In a bowl, toss the broccoli florets, sliced bell peppers, and shelled edamame with half of the olive oil, sea salt, and garlic powder.
Spread the vegetable mixture in a single layer on the prepared baking sheet and roast for 15-18 minutes until tender and slightly charred.
While the vegetables roast, pat the salmon fillet dry with a paper towel and season both sides with the remaining salt, pepper, and garlic powder.
Heat the remaining olive oil in a medium non-stick skillet over medium-high heat until shimmering.
Place the salmon in the pan and sear for 4-5 minutes on the first side until a golden crust forms.
Carefully flip the salmon and cook for an additional 2-3 minutes, or until the internal temperature reaches 145°F.
Arrange the roasted vegetables and edamame on a plate, top with the seared salmon, and finish with a bright squeeze of fresh lemon juice.
