When noodles are soft enough (but still slightly harder than al dente pasta), rinse them in cold water and drain. Make sure all of your ingredients are set up and divided into equal portions. Note: You’re cooking one portion at a time. Add 2 tbsp. oil to a wok or large non-stick pan. Heat on medium-high, until very hot. Add chicken (if using) and cook for 1 min, then add tofu and garlic. Cook for about 45 secs, stirring frequently. Garlic should now be brown. Stir in noodles, then add 3 tbsp. of sauce mixture. Coat noodles and meat well and stir vigorously to keep noodles from sticking. After about 2 mins, taste noodles to check if they’re soft enough. If not, add 2-3 tbsp. of water and continue to cook for a little longer.
