No rainbow carrots? Regular carrots work just as well.

Not a Brussels sprout fan? Broccoli or cauliflower also roast beautifully in their place.

Roast everything at 350 for about 20 to 25 minutes, flipping halfway through. While that’s going, season your flounder with salt, pepper, a little bit of plant butter or regular butter, and fresh lemon juice; light, bright, and simple.
