Sadly yes my health is not a good as it could be, but maybe getting out to Canberra is exactly what I need? They say a change is as good as a holiday and a 3 year paid holiday could be exactly what we both need!
We used to keep meals in the freezer for exactly the reason you state above. We also have meals that are reasonably healthy but not necessarily super healthy that we can prepare in 10 minutes again for exactly the same reason: getting home late and not wanting to prepare anything, plus there is always the age old fall back of breakfast cereal which can be eaten at anytime of day.
Also if we know that a single day or two are going to be late home, we plan our meals around that so that we already have food prepared that just needs reheating. So last night's and tonight's meals for instance were actually made on Tuesday (OK being veggie helps in this manner with no meat or fish being involved) and it will simply be reheated and added to. We have a super tasty mushroom bisque which has a good dose of cayenne pepper in it (nice and warming), it gets served with a marinated tofu which was also set marinating on Tuesday and is kept in the fridge covered under clingfilm. Served with some potato sourdough bread from the freezer and there is a quick evening meal. The bread is pulled from the freezer in the morning, the tofu fried up (in 1 teaspoon of oil) whilst the soup (portion not all) is reheated. It takes less than 5 minutes and we are sorted with a meal that is reasonably well balanced nutritionally. We have a whole range of soups and stews that we do this with. If they frozen, we just pull them out the morning we are due to be late home and let them defrost on the counter (winter and cold autumn/spring) and in the fridge in summer.
