Add the oil, salt, and garlic to a wok.  Heat up on low, and chop the peppers and broccoli rabe into bite sized pieces. Add the veggies into the wok and cover with a lid, stirring occasionally. 

In a bowl mix together the sauce ingredients - soy sauce, sugar, mushroom powder, cooking wine, and peanut butter. 

In a separate pot bring water to a boil and cook the noodles. 

Once the veggies are tender, add the diced cucumber, noodles, and the sauce to the wok and give it a nice stir. 

Top with the chopped nuts for serving.

Tip:  Leftover veggies are also a great option.
