Well here goes nothing, but really this taste fantastic.

The number of each veggie depends on how much you want to make. For my family 3-4 adults this is what I use.

1/4 cup of Olive Oil
1/3 tsp Rosemary (dried or fresh)
1/3 tsp Thyme

Mix in a bowl and let stand so that the flavors mix together.

2 Large Rutabagas
3 Medium Turnips
3 Medium Beets
2 Meduim Onions

Peel and chop all veggies but onion into bite size pieces
Quarter onions

Mix veggies with Olive Oil mixture and place in a roasting pan.
Roast veggies at 400 degrees until tender.
