Reserve 1 cup of the cooking water, then drain the gnocchi. Return the gnocchi to the pot along with the vegetables, lemon juice, butter, parmesan, pepper and 1⁄2 cup of the reserved cooking water.

Preheat oven to 350 degrees F. Cook gnocchi per package instructions, (do not cook for more than 2 minutes). Drain and set aside. Melt butter in a large oven-proof skillet.
