Cook thick rice noodles in heavily salted water - the brand I use has wrong cooking instructions - as it says you only need to cook for 7-8 minutes. I’ve found that I’ve needed to cook for 30-35 minutes to get to al dente

Cut water spinach into 1-2 inch sections, then in a separate pot blanch water spinach, and shock in cold water to stop the cooking process and keep them green
