meal prep for both me and my dog

I've been meal preping for both myself and my dog for a while now and I am starting to enjoy it!

For me: I used to buy from restaurant or from meal kit companies. They are either expensive or not quite to my taste or sometimes both.

For my furry friend: she used to only eat kibbles(rotate in different brands and variety though)

After moving to suburb area, eating out isn't as interesting as before(nothing interesting nearby) and the cost just keep increasing. So I started to batch meal prep, at first just for myself, but later realized it might be a good idea for my dog to eat fresh ingredients too, so I tried to get ingredients that is safe and healthy for both of us and use the cleanest way to cook(I also got a dehydrator to make jerky at home 😆), helps me to loss some extra weight and diversify what the dog eat(I rotate between kibble and homemade food + supplements)

Saved a lot of money compared to eat out(I have a script to calculate the average cost of a home made meal and the saving is so obvious), learned a bunch about ingredients/nutrition, and accumulated my own recipe library that can be shared by me and my pup.

What I want to keep improving is efficiency cos right now it can take 2-3 hours to prepare 5 human portion and 5 dog portion from start to end, maybe I should chop or prepare everything beforehand? or make more portions each time? I wonder how others think about improve the efficiency?
