When it's really hot and humid, I sometimes lose my appetite for rice. On those days, I like to make "noodle-y salads" - cold noodles + fresh vegetables + dressing/sauce.
A Korean version, with a spring onion, chives, carrot, tomato, cucumber, a spicy sauce and 냉면 (naeng myun - chewy noodles made with potato starch, sweet potato starch and buckwheat).
Another way: soba (buckwheat) noodles, cucumber, bell pepper, spring onion, carrots and peanut sauce.
I just use whatever veggies I have and if I'm feeling fancy, I'll add chicken or shrimp. In any case, it's a perfect meal for hot summer days.
