cook some chicken up. it's usually faster if you cut it into bite-sized pieced ahead of time. for the last minute or two, add large-chopped red (and/or green) peppers.
meanwhile, cook an entire box of spaghetti noodles. linguini would probably be good also, but I wouldn't use something thin like angel hair pasta. reserve at least 1 cup of the pasta water to use in the sauce.
in the same pan that you cooked the chicken, put about 1/2 cup of peanut butter (i used creamy, but chunky would be awesome) and 5 tablespoons or so of soy sauce. i also sprinkled some dried onion, garlic powder (NOT garlic salt, the soy sauce is salty enough!), and ginger.
don't trust this picture. It's after everything above is added, and before this next step. add at least a cup of the pasta water to the sauce mixture, more if it needs to be thinned. as with most of my recipes, i didn't actually measure any of those things. i just wrote down approximately what i used.
after the sauce is warmed, mix the pasta, chicken and peppers, and sauce together and you have a delicious meal!
tip: it's even better the next day. i really think that when I make this again, i'll make it the day before and just heat up the "leftovers" for dinner!
