No need to refreeze your food man.
Frozen food sucks!!!
My protein shakes are 800 cals a pop portable and none of that fake ass gainer shit either
Make a pot of brown rice it will keep for five days or so also boil a pot of beans or lentils. So there ready to go.
Same goes for your protein make enough to last 3-4 days and repeat.
Keep a Tupperware container of mashed potatoes or sweet potatoes in the fridge ready to go. Also keep veggies around that are quick to prepare/steam like broccoli or asparagus.
I always have almonds, peanuts or shelled pumpkin seeds to snack on they are high in protein and portable.
Oh then there are sandwiches, lunch meat or even Pbj.
Use your imagination and stop being lazy. I work 65 hours a week between two jobs and this is how I do and I'm a vegan. Being an omnivore is to easy!!
