Step 1

In a large saute pan on the stovetop over medium heat melt your butter. Add the sesame oil along with the mushrooms, onion, garlic, and bell peppers.

Step 2

Cook the mushrooms until they are lightly browned and the water has cooked out of them.

Step 3

Add the miso, soy sauce, Bachan's, and sambal to the pan. (If you don't have Bachan's, you can sub in additional soy or your favorite brand of teriyaki sauce.)

Step 4

Let that sauce mixture simmer for a couple of minutes and then add in your udon noodles to the pot. Add the water to the pan.

Step 5

Cover, and let the udon steam for a minute or two before using a set of tongs and breaking them up and mixing them in with the rest of the ingredients.

Step 6

Add the baby spinach to the pot and toss in with the pasta and vegetables. Cook until it is wilted and then remove from the heat.

Step 7

Garnish with sesame seeds and serve hot!
