Preheat oven to 450 degrees Fahrenheit (230 degrees Celsius).

In a small mixing bowl, stir together the lemon juice, oil, and parsley.

Place sweet potato spears on a Gefen Parchment Paper-lined baking sheet and sprinkle with salt. Drizzle a third of the lemon juice mixture over the sweet potatoes and place in the oven for about 25 minutes.

Remove baking sheet from oven and push the sweet potato spears to one side. Place fish and vegetables on the baking sheet and drizzle with remaining lemon juice mixture; sprinkle with salt and return to oven.

Bake an additional 15 minutes and remove from oven. You can also broil for the last five minutes, to achieve crispier edges if desired. Serve hot.
