Grow your own.
Last year we helped our little grandsons plant veg seeds thinking that they probably would not do very well as we usually just have flower garden and only a hanging basket of Tom thumb tomatoes by the back back door and a few herbs that look after themselves.
How wrong we were, Everything came up!
Yellow tomatoes, aubergines, peas, beans, cucumber in the garden not in green house and sweet corn in between sun flowers.
Had to get GN advice on the optimum time pick the sweet corn. ( it was delicious)
My grandsons enjoyed picking and eating their produce.
We are giving them a plastic green house this year.
So my thrift suggestion loopyloo is grow your own.
There is so much fruit and veg variety that can be grown in containers on patios and balconies.
