They might grow back but they will be crippled - possibly for a whole season or more.
You should cut your losses and replace them.
I've occasionally nursed plants back to life - but they were unique - I have some old populations of MDB, Sovs and Cambridge whatever and I occasionally find super plants that taste better than their neighbours. I would do anything necessary if any of them dried out before I'd propagated them (though in reality they might just be the few that still taste the same as the original plants - there is always a possibility of genetic drift in either direction - these are called 'sports').
But Elsanta? What are you thinking??
Dump them... Preferably try something better tasting and sod the lower yield (unless your entire "plot" is three containers on a patio).
Cheers.
