Killer olives

(from a really weird calendar we once had)

1 lb green or Greek olives
4 cloves garlic, sliced
2 t harissa or chili paste
2 T orange juice
2 T balsamic vinegar
Grated zest of 1 orange and 1 lemon
1/2 pint extra virgin olive oil
6 T chopped coriander

Whisk together all the ingredients except the olives. Add the olives and marinate for two days.
