It's important to know that chicken gizzards, especially fried ones, are going to be a little chewy in texture. You can do a few things to tenderize them before cooking, but it's just the nature of the gizzard. If you want something that's easier to chew, I suggest fried chicken livers. Fried gizzards and livers are often served at convenience stores that feature a fresh deli section. They are usually inexpensive, and the serving size is often generous. I prefer mine with a substantial amount of seasoned salt in the breading. Some people like to dip them in a hot pepper sauce, like Tabasco. I wouldn't call gizzards a health food, but they are definitely an affordable food.
