We bought a chicken for lunch the other day. I removed its legs and froze them for later use. The rest was roasted and we used the breasts to create 2 roast lunches each. The carcass was picked clean - see bowl on the left:
Mayonnaise and seasoning was added to those scraps and we had a lovely sandwich for lunch. The carcass was put into a bag and frozen for soup making a little later in the season.
