Preheat your oven to 400 degrees. Wash the potatoes, asparagus, and mushrooms, and pat them dry. 

Soften the Earth Balance, and stir in the Magical Seasoning Blend.    

Spray a half sheet pan with non-stick spray. Place the mushrooms stem side up on the sprayed sheet. Melt 1/3 of the seasoned Earth Balance, and brush it on the mushrooms. Place them in the oven and roast for 20 minutes.

Place the potatoes in a roasting pan that has been sprayed with cooking spray. Melt half of the remaining seasoned Earth Balance, and pour it over the potatoes. Mix to coat evenly. When the mushrooms have been roasting for 20 minutes, move them to the lower rack, and place the potatoes on the top rack. Roast for 20 minutes.

Roast the potatoes for 20 minutes, take them out of the oven and prick each one with a fork, then return potatoes to the oven. Take the mushrooms out, transfer them to a plate, and pour the juice from the pan over the mushrooms.

Spread the asparagus out on the empty mushroom pan, melt the remaining Earth Balance and seasoning together, and drizzle it over the asparagus. Toss to coat.

Check the potatoes. If they are done, remove them from the oven, and put the pan of asparagus on the top rack. If the potatoes are not done yet, place the asparagus on the bottom rack.

After 10 minutes, the potatoes should be done if they weren't already, so take them out of the oven. Move the asparagus to the top rack and use a spatula to turn the stalks over a few times. Continue roasting the asparagus for 10 to 15 more minutes until it is tender.

Distribute the vegetables onto the two pans, and place one under the broiler until the vegetables are perfectly browned.

Move the first pan to the lower rack, and brown the second pan of vegetables under the broiler. Serve and enjoy!
