Wilt the onions and garlic with a little of the stock in a heavy-bottomed pan large enough tohold the entire stew. Toast the spices in a dry skillet until just beginning to smoke. Transfer to a plate and set aside until cool. Add the spices and tomatoes to the onion mixture and cook until heated through. Blanch each vegetable in boiling stock until just tender. Add the vegetables and cilantro to the tomato mixture. Cook together until the sauce is the desired consistency.
