Hi hun, We have started making larger batches of chicken curry/chilli con carne/spaghetti bol and then freezing the leftovers for extra meals through the week (e.g last Saturday's curry, made an extra meal for Wednesday where we had jacket potato and chicken curry).
You can also pick up lots of cheap fruit and veg at Aldi. I think at the moment they have 6 veg items for 59p... whole cucumber, celery, tomatoes, new potatoes etc. We usually pick up lots of veg and then make a chicken noodle soup, one-pot casserole or a stir-fry.
We also try and pick up a large bag of potatoes each week from Costco as they come in handy for meals through the week e.g jacket potatoes, loaded potato skins, casseroles, egg and chips, sausages mash and gravy, etc.
Egg fried rice is a favourite of ours too and can be very inexpensive. I picked up a box of Mayflower curry sauce in B&M's for £1 and this makes a gorgeous curry sauce (tastes as good as a takeaway) but for only 2 syns per serving!
Hope these idea's help xx
