Place a large pot of salted water over high heat and bring to a boil. Once boiling, add the noodles and cook according to the package directions to al dente.
Toast sesame seeds and/or almonds in a skillet over medium-high heat. You can tell they're done when you can smell them!
While the noodles are cooking, heat the marmalade, tamari, chili oil and a pinch of freshly ground black pepper in a small saucepot over low heat. Stir to combine.
