You can have whatever you want whenever you want, there are no rules.
We make a “Thanksgiving” dinner here about once a month all year long.
We use chicken breasts instead of turkey, and make all the trimmings, mashed potatoes, grilled brussels sprouts, stuffing, cranberry sauce, corn, yams. I’d say it is the die hard, stuck in the box, traditionalists that never think they could have a holiday dinner and day of the year. haha
