Preheat oven to 375.

Place each fillet diagonally off-center on a parchment paper square.

Season with salt and pepper and arrange about ¼ C of vegetables over the top of each fillet.

Run one Sauté Express® Sauté Starter cube around the edge of each square of parchment and cut the remainder plus the unused cube into several pieces.

Evenly distribute the Sauté Express® Sauté Starter pieces over the fish.

Bring two corners of the parchment paper together and seal by pressing along the buttered edge.

Working a ¼" at a time, fold, roll and crimp the edges so that you have a nice tight seal all the way around the packet.

Place the packets on a baking sheet and bake at 375 degrees for about 12 minutes for medium-thick filets, give or take a few minutes depending on thickness.

Serve immediately.
