In a small sauce pot, over low heat, add the sesame oil, grinded szechuan peppercorns, crushed red pepper flakes, grated garlic, and grated ginger. Heat for 5 minutes, stirring occasionally, until garlic becomes fragrant. Carefully pour into a heat safe jar, such as a mason jar, add the toasted sesame oil, seal jar, shake, and place in refrigerator.

In a large pasta pot, bring water to a boil, and cook noodles according to package instructions to al dente consistency. Remove from pot, drain, rinse with cold water, add 2 tbsp sesame oil and toss to coat noodles. Set aside.

In a food processor, add in 2 tbsp of toasted sesame seeds and 2 tbsp of sesame oil. Blend on high for 30 seconds until seeds are made into a paste. Add the remaining ingredients in with the sesame paste: creamy peanut butter, rice vinegar, soy sauce, honey, garlic, ginger, sambal chili sauce.Blend on high for 30 seconds until smooth. Taste and adjust flavor if necessary, i.e. more peanut butter if desired. 

Transfer noodles to a large bowl, start slowly pouring the sesame sauce onto the noodles, while tossing noodles with tongs to coat all the noodles. Reserve about 1/4 cup (see note). Grab szechuan chili oil, give it a shake, add 2-3 spoons into the noodles, toss to coat. Reserve the rest for those who want to add more individually to their dish.

Garnish with fresh julienned cucumber to cut the heat and fresh cilantro leaves. Serve with lime wedges and enjoy!
