From Robin Miller's Quick Fix Meals, this is quick and easy to make. You will probably have extra sauce, so feel free to increase the amount of salmon and make salmon cakes with the leftovers, as Robin suggests.
preheat the oven to 400°F Coat a shollow baking dish with cooking spray. Season both sides of salmon with salt and pepper. Place salmon in prepared baking dish.
Combine Dijon mustard, honey, water, lemon juice, mustard powder and garlic in a medium bowl. Reserve 1/2 cup, and pour remaining sauce over the fish in the pan. roast the salmon, uncovered, until fork-tender, about 15 minutes.
Stir the dill into the reserved sauce and serve with salmon.
