Why do green bell peppers even exist? They are simply unripe red bell peppers, inferior in every way to their ripened brethren. Green bell peppers are bitter and thin, and hard to choke down. Red bell peppers, on the other hand, are sweet and plush, and when cooked, turn lush and silky. How many times have you ordered Chinese and been left with a pile of uneaten green bell peppers in each dish? Red bell peppers even have more vitamins and antioxidants than green. Let the peppers ripen!
