1Preheat your oven to 375°F (190°C).
Place the trout fillets on a baking sheet lined with parchment paper.
In a bowl, mix the olive oil and lemon juice together.
Brush the olive oil and lemon juice mixture over the trout fillets.
Season the fillets with salt and pepper to taste.
Arrange the mixed veggies around the trout fillets on the baking sheet.
Drizzle a little more olive oil over the veggies and season with salt and pepper.
Bake in the preheated oven for 15-20 minutes, or until the trout is cooked through and flakes easily with a fork.
Remove from the oven and serve immediately.
