Thaw salmon and pat dry. Season with salt and pepper.
In a small bowl, whisk together olive oil, Dijon mustard, minced garlic, and a squeeze of fresh lemon juice.
Place the salmon filet on sliced lemon on a piece of parchment paper. Optional to add additional veggies here.
Brush the olive oil mixture over the salmon filet.
Wrap up the parchment to completely cover the salmon and tuck the sides under or tie to seal.
Bake the salmon for 15 minutes at 350 degrees.
Serve salmon over greens with a side of sourdough bread.
Enjoy!
