Mool Naeng Myun
There is an array of cultures that have dishes that help to address exactly this issue. Most famously is Gazpacho, which in its popularity is widely available now in cartons at the supermarket. If you are tired of the perennial favourite, may I suggest Mool Naeng Myun?
Mool Naeng Myun is soup served cold with noodles in a broth. After that, there are many variations of accoutrements, but typically it comes with a hard-boiled egg, cucumber slices, radish, Asian pear, some variety of protein and on the side some vinegar and mustard for the diner to season to taste.
I am not suggesting attempting to make this yourself as there are many components, but if you have a vibrant K-town or know of a Korean restaurant, treat yourself to this savoury and refreshing dish, skip the cooking and prep, (honestly, who can be fussed!? I am melting), and enjoy something that is a little more hearty than some pureed vegetables.
If you are in NYC, check out Dons Bogam (shoutout to @linarose.lee for introducing me to this place!) and here in London definitely go to Hozi in Holborn., and finally, if you are in the SF Bay area, you cannot beat my family's place, Beque Korean Grill! Happy adventures and happy eats!
