As a food stall owner, I recommend fried chicken fillet as a snack suitable for one person. Fried chicken fillet is simple to make, delicious and low in cost, which is very suitable for one person to operate. Besides, we can also consider introducing other simple and cheap snacks, such as French fries and fried chicken wings. When choosing snack items, we should take into account factors such as simple production, delicious taste and low cost, so as to attract more customers.
