Get yourself to B&Q, and see what veg plants they've half killed this week Or a garden centre? My local one still had courgette, pea & runner bean plants amongst others.
Otherwise, there's still winter crops you can sow; PSB, cabbages, kale, swedes. Also beetroot & carrots can still be sown now. Then there's over-wintering onions, garlic & shallots in September.

“Of course it is happening inside your head, Harry, but why on earth should that mean that it is not real?”
