Aldi, 3 peppers for 99p (sometimes they do them for 69p), spinach for less then a £1 (can't remember exactly how much), radishes 39p, baby corn, asparagus 99p ... loads more stuff!
I don't know if anyone lives in/near Manchester city centre as there is a brilliant market stall. Huge bunches of coriander and spinach for 50p ago, 7 corn on the cob for £1, spring greens which they do by weight but are HUGE, celery 60p, baby corn 60p, pak choi roughly 2 bunches for 41p (again, done by weight) etc. PM me and I'll explain the exact location.
