Preheat oven to 450°F. Place a large baking tray in the oven to warm up.
In a large bowl, toss the frozen vegetables in olive oil, salt and pepper.
When the tray is hot, carefully transfer the seasoned vegetables onto the tray and spread out into an even layer, making sure the vegetables are not overlapping.
Roast for 15 to 30 minutes depending on the vegetable.

Notes
Storage: Roasted frozen vegetables are best eaten straight away, but they will keep well for up to 3 days in an airtight container in the fridge and can be reheated. Do not refreeze because the texture will suffer.Photo Credit:Erin Jensen
