Cook rice noodles per package, not too soft, drain, rinse to cool, set aside
Whisk all sauce ingredients together and set aside. (may need to heat up to incorporate p'nut butter)
In a large skillet(nonstick) place reg onion, carrot, 1/2 gr onion, meats or veg equiv, optional veg, a little water and saute to just crisp tender. Don't let scorch, add water a little at atime if needed but veg should provide enough. You could use oil here for the saute if you'd like.
add noodles and sauce and toss well to incorporate (cooking tongs help well here)
Add basil and bean sprouts and toss until heated through
At plating/serving sprinkle with chopped p'nuts and remaining green onion.
