Can I roast sweet potato, carrot and parsnips in the same dish?
Yes I love mixed roasted root vegetables. Regular potatoes, turnips are also good in the mix. I like to ad thick wedges of onions too.
Jamie Oliver did an interesting mix to serve with lamb:
Quartered fennel, with its own leafy tops
Quartered red onions
Whole baby turnips
Butternut squash, cut into chunks
Jerusalem artichokes, scrubbed and halved
1/2 (14-ounce/400 gram) can chick peas, drained
Salt and freshly ground black pepper
