Each to their own of course but we tend to eat both cold meat and make
things like curries etc, plus using the carcass from a Turkey / Chicken to
make stock for soup with small bits of meat going into that.
I recently tried using Sous Vide to reheat gammon slices and pot roast meat
previously cooked. The gammon had been frozen the pot roast just popped in
the fridge after cooling etc the day before ( we needed to eat at lunch
time and it was easier to precook the day before).
I used the Sous Vide function on my Instant Pot. Taste / texture was fine.
The only down side was getting the quantities right. I cooked a large pot
roast. Estimated what I thought I needed for the lunch, allowing a bit over
for ‘seconds’, and froze the rest.
