A nice, hearty root vegetable side dish.
Most cookbooks I have seen recommend peeling the turnips before cooking. I usually don't bother. Try them both ways.
Boil the cut turnips in water for about 10 minutes - they should still be firm but not hard. Drain.
Saute the garlic and onion in the oil. Add the turnips and seasonings, saute for 5-10 minutes until they are the desired level of browned.
