"No onion toppings. Every restaurant is facing a shortage of onions. You see the signs everywhere."According to official statistics, the price of onions surged in the Philippines to around 700 pesos ($12.80; £10.40) per kg last month.That is more than the cost of meat, and the Southeast Asian country's daily minimum wage.Although prices have eased in recent weeks, onions are still a luxury for many consumers, says Rizalda Maunes, who runs a pizzeria in the central Cebu city.
