To Roast Peppers:

Using a long-handled fork char the peppers over an open flame, turning them, for 2 to 3 minutes, or until the skins are blackened. (Or broil the peppers on the rack of a broiler pan under a preheated broiler about 2 inches from the heat, turning them every 5 minutes, for 15 to 25 minutes, or until the skins are blistered and charred.) Transfer the peppers to a bowl and let them steam, covered, until they are cool enough to handle. Keeping the peppers whole, peel them starting at the blossom end, cut the tops, and discard the seeds and ribs. (Wear rubber gloves when handling chilies.)

In a bowl or resealable heavy plastic bag combine the mozzarella, the oil, the garlic, the vinegar, the oregano, the basil, the thyme, and salt and pepper to taste and let the cheese marinate for at least 4 hours at room temperature or chilled overnight. Thread a mozzarella cube, an olive half, and a roasted pepper square onto each of the wooden picks and arrange the brochettes on a platter. The hors deoeuvres may be made 4 hours in advance and kept covered.

Makes about 50 hors deoeuvres.
