Op is your budget for 2 weeks for all food and drinks?
Do you need to include packed lunches for yourself and DD?
Do you have in basic store cupboard ingredients?
I have some meal ideas that using tesco online shop come in around £21 for 14 main meals and there will be some leftovers for lunch some of the days. The £14 left over could cover milk/ bread/ teabags etc but it would be tight.
Meals ideas are :
Ham fried rice, sausages and mash, mince and potatoes, chorizo potatoes (similar to patatas bravas), veggie risotto, lentil and carrot soup, ham noodles, tomato soup with cheese toastes, (micro)baked potatoes with beans and cheese, baked potato with tuna mayo and sweetcorn, chilli and rice, bolognaise, macaroni cheese.
I know the above seems a lot for £21 but I do make the above recipes frequently and thats for 2 adults and a 6 year old so you would have leftovers for lunch from a lot of them.
If you want anymore details let me know.
