Hi Spring79
I guess it was expected that people may diet in couples or with family hence the portion sizes.
I am doing this on my own and what I am doing is either :
1. For hot meals, finding freezable recipes e.g. Aubergine Lasagne, making the whole thing and assembling in 4 individual tin foil trays for cooking, freezing, then reheating at a later date, or putting one uncooked in the fridge for a meal later in the week.
2. For cold meals (salads), just halving or quartering the quantity for that recipe and have the same meal in a couple of days to save on buying too many ingredients
3. I plan my meals weekly and try to make sure that for that week there are many of the same ingredients in the meal so I can use it in a few recipes. Then the next week, choose different recipes so it doesn’t get too ‘samey’
Hope that helps?
