Preheat oven to 425 degrees. Line a large baking sheet with parchment, or grease with a bit of olive oil.
To make the hot honey: combine all ingredients in a microwave-safe jar or glass. Heat 1 minute on high. Stir, then zap an additional 20-30 seconds until the granules dissolve. Leftover hot honey will keep up to 2 weeks in the fridge.
On the baking sheet, toss the potatoes with 1 tablespoon olive oil and a big pinch each (about 1 tsp) salt and pepper. Spread in an even layer on the sheet and roast 10 minutes.
In a food processor, combine the pecans, panko, lemon zest, garlic, and a pinch each of salt and pepper. Blitz until crushed into crumbs. The breading needn't be the texture of meal, but shouldn't have any huge chunks. Pour into a shallow bowl.
Pat the salmon very dry with paper towels and lay onto a large cutting board or plate.
In a small bowl, whisk the hot honey, lemon juice, dijon mustard, smoked paprika, and a pinch of salt and pepper. Brush all sides of the salmon generously with the sauce.
Dunk each filet into the pecan breading, pressing additional crumbs to fill in the crevices. Some will fall off - don't worry, baking will make them adhere more cleanly!
Push the potatoes to one side of the baking sheet. Add the asparagus to the opposite side and toss with 1 tablespoon olive oil and a pinch each of salt and pepper. Nestle the salmon filets in the center. Roast an additional 10-12 minutes. If desired, switch your broiler to high for the final 2-3 minutes of roasting time to achieve a little crunch. Do not broil if you used parchment!
Serve the salmon, potatoes, and asparagus with additional hot honey.
