Heat up the grapeseed oil in a saucepan over high heat until the oil is shimmery and hot, but not smoking.
Add the green onions, ginger, garlic and shallots at once, but be careful, the oil will bubble and splatter. The onions will sizzle and wilt almost immediately and turn a bright green.Take the pan off the heat and stir the sauce with a wooden spoon.
Add the fish sauce, sesame seed oil, rice wine vinegar, soy sauce, honey, crushed red chile pepper and salt to taste.
Let sit for 15 minutes, then toss with your favorite noodles. I used fresh Chinese egg noodles.
