For authentic flavor, use sambal oelek (a mixture usually made of chiles, brown sugar and salt found in most ethnic groceries) in place of hot chili sauce.
Bring 6 cups water to a boil in large nonstick skillet. Add noodles, stir to separate, then cover and remove from heat. Let stand 6 minutes to soften. Drain and set aside.
Whisk together teriyaki sauce, 2 Tbs. hot water, peanut butter and chili sauce in small bowl.
Wipe out skillet, add sesame oil, and heat over medium-high heat. Add garlic and ginger, and stir-fry 30 seconds. Add snow peas and stir-fry 3 minutes. Add tofu, and stir-fry 1 minute. Add teriyaki mixture and cook 2 minutes, or until sauce thickens, stirring occasionally.
Add noodles, and gently toss with fork 2 to 3 minutes, or until noodles are coated with sauce and heated through. Sprinkle with cilantro and peanuts. Serve hot with lime wedges.
