This is much better using whole wheat liguini...and a few modifications. Omit using the cooking liquid because there is usually enough water from the veggies and noodles. To add more flavor...omit garlic sauce and use crushed red pepper flakes (I crush some dried thai chilis) to taste and grate in 2-3 cloves of garlic, a two inch piece of ginger, and a little lime zest. I also use the juice of 1/2 a lime. Wisk in with the soy sauce, peanut butter, and a couple of tablespoons honey or brown sugar. The sweet and spicy combo is great. You can also go all veg or saute some firm tofu in some sesame oil before adding the veggies and it is still very delicious.
