Marinate beef for 1-2 hours in tamari, sesame oil and minced ginger. Remove excess marinade before cooking.Heat a saute pan on high heat and add enough olive oil to cover bottom of the pan. Saute beef until just done, about 4-5 minutes per side.Assemble salad ingredients (cabbage, romaine, pepper and almonds) on a platter. When beef has cooked, allow to rest a few minutes, then slice it on a diagonal. Whisk together dressing ingredients (tamari, oil, vinegar, peanut butter, lime, garlic and stevia), and combine with vegetables. Place steak slices on top of salad, and serve.
