Meals of the week

My 10 year old had an interesting idea about how to switch up our weekly meal rotation. He had the idea for a "worldly Wednesday" which is foods from different parts of the world, and a "Throw Back Thursday" which would be meals popular from different decades. I love the idea, just not sure exactly how to implement or what to make... I need easy meals to set up and make because I also have a very attached 4moth old and can only put him down long enough to chop some onions or the like lol. Any ideas would be great appreciated ❤️❤️
