I find rather than making a big batch of raw chop that it’s now easier for me to just make extra of any and every veg and grain I’m having for tea and just pop a few portions into snap bags and then freeze- I don’t ever use salt or butter when I cook most things that Burt can have and I bake/roast most of my veg without oil so this is also fine for Burt. Doing it this way I find I can mix the pre prepared frozen veg and grains each morning and add some fresh grated or chopped raw veg and sprouts and make it varied every day with minimal effort put in.
I usually have froz peas, froz corn, froz spinach and kale from supermarket with no added salt- I boil or roast beetroot, dice and freeze, mashed steamed sweet potato, roasted and mashed or chopped sweet potato, pumpkin, carrot, also a heap of little bags of different grains- rice, quinoa, chickpea, buckwheat.
Any fresh stuff I now do as it’s needed which is usually simply a few minutes each morning - this way I don’t have Burt getting all fed up with the same foods and I’m not ever feeding him soggy week old food, I don’t get ice build up on the food (our freezer gets opened way too much!) and I always have something to make a tasty quick breakfast from.
