So I suggest that eating some fast food such as egg cakes, sesame cakes and pancakes in the morning is convenient, relaxed, inexpensive and cost-effective; Eat something good at noon, such as: meat buns and steamed bread, which saves money and does not waste time; Eat some light food in the evening, such as wonton (sold outside), which is not too expensive and healthy. I suggest you eat it this way. But the key is to find food that suits your taste, is enough for you to eat and can make you healthy.
