Pre-heat the oven to 400 degrees. Wash and slice your potatoes. Leave the skin on.

In a bowl, toss the potatoes with 1 tablespoon lemon pepper seasoning, 1 tablespoon of olive oil, and some salt and pepper. Spread the potatoes out in one layer on a large oiled cookie sheet. Top with one tablespoon of cubed butter. Roast in the oven for 15 minutes.

While the potatoes are cooking, prepare the salmon. Pat the fish dry with some paper towels. Coat the salmon with 1 tablespoon of olive oil. Now rub the salmon with 2 tablespoons of lemon pepper seasoning, and salt (if needed) and pepper. Now top with 2 tablespoons of cubed butter.

Slice the 1 1/2 lemons into rounds. Reserve half a lemon for squeezing onto the fish when serving. After 15 minutes remove the potatoes from the oven and push them to both ends of the cookie sheet to make room for the salmon.

Place the salmon in the center of the cookie sheet and top with lemon slices.

Place the cookie sheet back into the over for an additional 20 minutes (reduce the time if cooking less than 2 pounds). After 20 minutes, remove from the oven and serve with extra lemon!
