Sausages with Carrots, Apples, and Onions

Variation: A mixture of beets, sweet potatoes and fennel would also be delicious with the sausages.

2 large Granny Smith apples cut into cubes
1 1⁄2 pounds small red potatoes
1⁄2 pound baby carrots
1  large red onion cut into wedges
2  tablespoons parsley leaves chopped

Preheat the oven to 400 degrees. In a large bowl combine the apple cubes, potatoes, carrots, onion, parsley and rosemary.
