How do you infuse the flavor of a sauce into chicken?
You can't do it, it's physically not possible. Your meat will always taste of meat, not of sauce. Meat is not some kind of sponge which can soak up sauce, it's a dense muscle. 

If you want more flavorful meat, you can buy more flavorful meat. Most meat you can get in the supermarket is tasteless, because 1) people don't really like meat flavor if they are not accustomed to it (see the recent mutton question), 2) it's cheaper to raise tasteless meat (young chicken vs. soup hen) and 3) you need a fattier meat to have more flavor, but people prefer lean meats nowadays. Still, the meat will then taste of meat, not of sauce. 

If you find your food way too tasteless, you can also consider preparations such as a meatloaf, where you can physically mix spices into the protein.
