well in my country there's a thing called "box diet" (you can order healthy meals neatly packed in boxes)... but it's bit pricey. Maybe you have something simmilar where you live?

And yes, microwavable foods are horrible and do horrible things to your body... including whacking up your mood.

The easiest food to prepare for me is meat with potatos/pasta/rice... I mean, put it in over, with some spices sprinkled on it... and then you just take it out. Make some basic veggie salad to go wiht it (chop up some veggies).

Eggs are healthy and nutritious.

Or frozen veggies that you simply fry on pan for few minutes. Easy, and if you prepare them on butter, pretty great.

Yeah, it's not three minutes meals, but I think the effort is worth it.
