The fear for summer vacation

I'm bracing for the summer vacation.

My son's summer vacation will start the day after tomorrow. So, I'm afraid of making every meal. I have kept some fish, meat and vegetables in my fridge for making them, but I still feel the preparations are not enough.

In the U.S. dramas, people buy meals at restaurants or order pizzas frequentry. Of course, I can do the same like them, but it's not so cheap here in Japan. In addition, there are no Trader joe's/Whole foods*1 in Japan and it's hard to find frozen foods made with organic ingredients. So I have to make meals by myself if I want to eat something trustworthy and low-cost.

How can I enjoy this task? I need replicators*2 to solve this problem. 

*1 Both of them are supermarkets in the U.S. which deliver various organic foods.
*2 A machine for creating meals in the Sci-Fi drama, StarTrek.
