01 - Preheat oven to 400°F (205°C) and line a rimmed baking sheet with parchment paper.
02 - Combine honey, Dijon mustard, whole-grain mustard, olive oil, lemon juice, and minced garlic in a small bowl and whisk until smooth.
03 - Arrange salmon fillets on the prepared baking sheet, pat dry with paper towels, and season both sides with salt and pepper.
04 - Brush the tops of each fillet generously with the honey mustard glaze.
05 - Bake salmon for 12-15 minutes or until just cooked through and easily flaked with a fork.
06 - While the salmon cooks, pulse broccoli florets in a food processor until the pieces resemble coarse rice.
07 - Heat olive oil in a large skillet over medium heat. Add chopped shallot and cook for 2-3 minutes until softened. Add broccoli rice, season with salt and pepper, and sauté for 4-5 minutes until vibrant and just tender.
08 - Plate the broccoli rice and top each portion with a glazed salmon fillet. Serve immediately.
