yes, you can buy breadrcrumbs
heres an easy way
first, with a meat mallet, pound the breast to an even thickness (for quicker cooking AND even cooking)
set up 3 deepish dishes and heat an inch or so of oil to about 370F (if youre using a fryer or have a thermometer, otherwise, medium-high usually does it)
season meat. i like salt, pepper and essence, or whatever you enjoy
dish one: flour.
dish two: eggwash (1 egg + 2tbls water for every 3 servings) and whisk until smooth
dish three: flour or breadcrumbs (depending on what you want/have)
lay meat in dish one, coat evenly, shake of excess (important!)
using a fork or tongs (else youll get damn messy) lay coated meat in eggwash, cover evenly, again, shake of excess
dip in flour or breadcrumbs, coat well, allow to rest for 2 or 3 minutes
check oil readiness by dropping a pinch of flour in, if it sizzles, its ready.
add meat. if adding more than 2 pieces, you should up the heat slightly to adjust for heat absorbtion
for an evenly pounded breast of chicken, id go 4 or 5 minutes a side, depending on how thick you made it (id rarely go 3, youd have to have it quite thin) a meat thermometer is great in this case. should be golden brown then and quite crispy
thats good for a homestyle fried chicken breast, or chicken strips, or if you like, a chicken-fried steak (like a thin top round or cube steak), porkchops, etc.
