A dinner that involves many different items that have no relationship to each other. Like in the movie Grandmas Boy where he gets a huge display of odd food.
Sister: Hey go look in the kitchen mom made a real grandma boys dinner today.
Brother: Wow yea she did today we have mac and cheese, pot pies, a frozen pizza, and cake
