Preheat the oven to 425F and line a very large baking sheet* with parchment paper or foil (for easy clean up). If using foil, lightly grease the foil to ensure your food doesn't stick then set aside.

In a large bowl, whisk together the olive oil, 2 tablespoons of dijon mustard, apple cider vinegar, herbs, salt, and pepper. Add in the broccoli and toss to coat.

Spread the broccoli in a single layer on the prepared baking pan and roast for 15 minutes.

While the broccoli is roasting, prepare the salmon.

Spread the remaining 2 tablespoons of dijon mustard on top of the salmon filets then sprinkle 1 teaspoon of everything bagel spice on top of the mustard. Set aside.

After the broccoli has roasted for 15-minutes, remove it from the oven, give it a quick stir then nestle the salmon filets into the broccoli.

Return the pan to the oven and cook another 10-12 minutes until the salmon is cooked through or reaches 145F and the broccoli is browned and crispy around the edges.

Remove the pan from oven and serve immediately or allow everything to cool completely before paking into 4 containers for meals later in the week. Store in the refrigerator.
