I can`t imagine not using chili paste in this it makes it! I used chili paste with garlic and it was yummy. If you don`t use it I do suggest adding garlic/ I couldn`t get whole shiitaki mushrooms only sliced which is really hard to skewer but I did it. Also I topped the dish with the skewerd mushrooms at first then mixed it into the noodles for the noodles did need the flavor from the mushrooms. I used snap peas. The noodle were dry so I did add some of the pasta water to it. So making a bit more sauce would be good as well. But all in al I enjoyed it a lot.
