The cost of preparing a vegetarian thali at home declined 3 per cent (month-on-month) in December, while the cost of a non-vegetarian thali is estimated to have increased at a similar pace, according to a report on Monday. 

While tomato prices fell 12 per cent on-month, helped by fresh supplies from Madhya Pradesh, Maharashtra and Gujarat, the cost of non-vegetarian thali grew at a faster pace due to an estimated 11 per cent on-month increase in broiler prices on a dip in production triggered by a cold wave in the north, said the CRISIL Market Intelligence and Analytics report.
