Lidl have cabbages and blood oranges as part of their cheap fruit and veg offer this week.
Cabbage 35 p, 4 blood oranges for 99 p, lemons would be priced as normal, so it might all come in at around a pound for the selection mentioned in the OP.
The mention of the show tomato has reminded me that the doctor that was on BBC Breakfast in the 'how are we doing with covid' this morning had what appeared to be a decorative pineapple behind her. I wonder if she is a Mumsnetter?
