Onion Bhajiyas are a popular Indian snack made with sliced onions, gram flour, and spices. The onions are mixed with a batter made from gram flour, rice flour, and spices, then deep-fried until crispy and golden brown. These crispy fritters are perfect for rainy days or as an appetizer for parties. Serve them hot with mint chutney or ketchup for a delicious and flavorful snack.
