Do you have a separate meal menu set out when working as a maunza?

If you start with Maunzaro
Rather than eating just anything as usual
I think it would be good to pay a little more attention to my diet, so I am looking into it.

But when I actually tried to plan the diet
I'm worried that I'll end up eating the same food every day.

A menu that is easy to prepare and eat while working.
Are there any of you who have put together a meal?

If there is a method that made it easy to do consistently
I would like to refer to this.
