Preheat the oven to 400°F (200°C).

Place the store-bought pies on a baking sheet and bake according to the package instructions, usually around 25-30 minutes.

While the pies are baking, prepare the vegetables. Peel and chop the potatoes, carrots, and onions into bite-sized pieces.

Toss the vegetables in a bowl with olive oil, salt, pepper, and dried herbs (such as rosemary or thyme).

Spread the vegetables on a separate baking sheet in a single layer.

Roast the vegetables in the oven for 30-35 minutes, or until golden and tender, turning halfway through.

Serve the hot pie with a side of roasted vegetables.
