Who can help me design some nutritious lunches that I can eat in summer?
I think, first of all, you should look at your aunt's eating habits. Do you like light or greasy food? You can cook a good meal according to your aunt's preference, but what you need every day is loofah soup, mung bean soup and the like. Occasionally, you can bring some fruit and vegetable salad to make a side meal. Personal opinions can be adopted.
