How to Make It
In a large bowl, toss the tofu with 2 tablespoons of the soy sauce and let stand for 10 minutes.
Bring a large saucepan of water to a boil. Add the chow mein noodles and cook until they are al dente. Drain and rinse the noodles under cold water. Shake out the excess water and add the noodles to the tofu and soy sauce.
Meanwhile, in a blender, combine the remaining 1/4 cup of soy sauce with the peanut butter, chicken stock, rice vinegar, chile-garlic sauce, ginger, garlic and sesame oil and puree until a smooth sauce forms. Pour the peanut sauce over the noodles, add the sliced red bell peppers and scallions and toss. Garnish with cilantro and serve.
