Bring a pot of water to a boil for the pasta. Add salt and cook pasta to al dente.
When the pasta goes into the water, heat the oil in a large skillet over high heat. Add chicken or pork, brown and transfer to a plate.
Add leeks and mushrooms to the skillet and stir-fry 2 minutes. Add garlic and ginger, and cook a minute more. Stir in Tamari, agave syrup or honey, lime zest and juice, and hot sauce to taste. In a large serving bowl, toss veggies with the meat, noodles and lettuce to combine.
Garnish with cilantro or basil and serve with lime wedges alongside.
