Roasted Garlic Salmon with Potatoes & Asparagus

This is a kind of cheat one. I usually don't use instant potatoes, but they've come a long way!

4 salmon fillets (about 1 1/2 lbs)
2 pkg (about 4 oz each) roasted garlic instant mashed potatoes
1 bunch asparagus, woody ends removed
1 tbsp oil
1/2 tsp each pepper and salt

Heat oven to 425. Line a baking sheet with foil or spray with cooking spray (or both!). Put the salmon, skin down, on the pan. Reserve 1 cup of potato flakes from one package, sprinkle what's left over the salmon. Arrange asparagus around salmon, drizzle all of it with the oil, salt and pepper. Bake about 15 mins, until the salmon flakes.

Meanwhile, heat 3 1/2 cups of water to a boil, remove from heat and add all the potato flakes.
