I usually have a mixture of old stand-bys and Pinterest inspired ones - I pin stuff when I see it, then before I do a menu plan I'll have a quick look to see what I want to add in.
They're not always a success - DSS has asked me if we can please not have the butternut squash pasta again as he wasn't keen, so it'll just me me and DS using the leftovers up in the freezer! He's pretty adventurous though, so is always up for trying new recipes (unlike DH who likes boring, plain things
)! DH works away about 4 nights a month, so I tend to reserve trying out more interesting recipes for those nights!
Lunches I'll usually have a fair idea about what we'll have, but they're less regimented e.g. I'll buy a packet of ham and know it'll do a few days, but which ones might depend on if there's any leftovers which can be reworked for lunch (like pasta for a salad, or extra sausages).
For breakfasts we were having a lot of smoothies in the summer, but the toddler and I are now back to porridge most days, with DSS on cold cereal /toast depending on what he feels like. DH will either have granola or coco pops, or takes one of those porridge pots to work if he's off early. He buys his lunch most days, so that's not included.
I usually have a few things on the plan that are from the freezer, that way if I need to re-jig it nothing fresh is going to waste.
