I often meal prep when I have time, like whole in the morning or the afternoon for my family's bento box and for dinners. It is now in trend among Japanese house holds so I could refer many recipe website, cook books often see in TV shows.
I had whole Sunday afternoon at this time without busy schedule so I could prepare several kinds of food for the following week. I store them in a fridge that useful for bento box. I don't need to be busy in early morning.
I prepared those items
Cooked green Komatsuna mixed with fried tofu and little dried shrimp
Fried rice ( using garlic and ginger sauce)
Simmered daikon radish and chicken with soy sauce seasonings
Mapo tofu, minced pork, scallions and tofu cook with chinese miso paste
Cooked spinach and carrot julienne
Carrot rapeets carrot julienne marinade with EVOO, lemon, salt and peppers
I believe those food support my busy time next week.
