Thanksgiving leftovers burger with a ground cooked-turkey patty and a stuffing patty

Cut the cooked Cajun turkey breast to fit and grind it.

Add egg as a binder, a little more Cajun seasoning, and crushed French fried onions to help it bind, until there is just enough moisture and binder to form a patty. Shape the patty.

Shape leftover sausage stuffing into a patty; it need not be thick or the same size.

Oil the flat top and put down the turkey and stuffing patties; since the turkey is cooked, it only needs browning and some crisp, and will barely shrink. Toast the buttered brioche bun alongside.

Flip the patties, put cheese on the turkey patty, and cover with a lid to melt.

Build: mayo on the bun, the turkey patty, the stuffing patty, warmed mashed potatoes, French fried onions, then gravy.
