Bring a large pot of salted water to a boil add the pasta and cook until just shy of al dente. Drain.

While pasta water comes to a boil, heat the stock, oil, sliced lemon and tamari sauce and allow to reduce over medium-high heat, about 7 to 8 minutes. Toss cooked pasta with sauce for 1 to 2 minutes to absorb flavor, add in reserved zest and chives then serve as first course or a side dish. Spice it up with pepper or hot sauce to pass at table.
