Just voted again for you! If you win the contest, will you be sending (those who voted) some tempting Mississippi Mud Cake??? 😉
I have the same issue with overplanning. We just had a friend stay with us last week from Italy. He was surprised at all the food I was serving. It’s fun and I wouldn’t change the overplanning part at all.
