Fill the 5-quart pot with water and bring to a boil on high heat. When the water is boiling, add spinach and blanch for about 1 minute. Remove spinach from pot with the stainless steel metal strainer and put in colander. Squeeze spinach tightly to remove the excess water and place in a medium bowl. Add 1 tsp of soy sauce and 1 tsp of sesame oil and mix well so the spinach is no longer stuck together.
Add the sweet potato glass noodles to the same pot of water and cook for 5 minutes, stirring occasionally. Strain the noodles into the colander and rinse with cool water. Using the kitchen shears, cut the noodles into smaller pieces. Add the noodles to the large bowl along with half of the soy sauce, half of the sesame oil, and half of the coconut palm sugar. Mix well with your hands to combine. Add seasoned spinach to bowl.

Add 1 tablespoon of canola or sunflower oil to the pan and cook the yellow or white onions with ¼ tsp of salt for 5 to 7 minutes. Add the cooked onions to the bowl with the noodles.
Add 1 tablespoon of canola or sunflower oil to the pan and cook the mushrooms with the garlic and ¼ tsp of ground black pepper for 5 to 7 minutes. Add the cooked mushrooms to the bowl with the noodles.
