from Jamie Oliver's The Naked Chef Takes Off
1 lb fresh raw beets, scrubbed (I cut them up a bit as it says golf-ball sized and mine weren't)
10 clovers garlic, squashed and peeled
a handful fresh oregano, leaves picked from stems
salt and pepper
a good glug balsamic vinegar (it says 10 Tbsp, I didn't use nearly that much)
a good glug olive oil (same story -- it says 6 Tbsp.)
Preheat the oven to 400 degrees. Tear off around 5 feet of aluminum foil and fold it in half to give double thickness. Place beets in the middle of the foil and everything else on top, folding the bottom up some before adding the liquids. Then seal the foil around the beets. Put on a baking sheet, place in the oven, and cook around an hour, until tender.
