Many people incorrectly believe that "kosher" is a style of cooking but this couldn't be further from the truth. Kosher simply refers to foods that are prepared following the laws of kashrut (Jewish dietary laws) which does not dictate the style of foods eaten by Jews outside of prohibiting certain types of foods. As such, religiously observant Jews will only those those foods that are Kosher.
The basic rules of kashrut are:
1. Land animals must have split hooves and chew their cud.
2. Fish must have scales and fins.
3. Birds must not be amongst the list of forbidden birds in the Torah and must not be hunters.
4. Meat and dairy cannot be combined in any way.
5. Consumption of blood is forbidden.
Now, to answer the question as to what foods Jews eat, this varies greatly depending on what part of the world said Jews are from. The types of foods eaten by Jews from Eastern Europe will be different from those in Southern Europe, from those in India, Northern Africa, Yemen, Iraq, Israel, etc.
Foods will even vary by region within the same part of the world, a dish that is eaten by Polish Jews may also be eaten by Russian Jews, however, the ingredients or how that specific dish is made will be different.
American Jews usually eat plenty of matzoh ball soup and latkes(potato pancakes) lox and bagels.
Israeli Jews eat middle eastern foods... humus... dolmades... different types of fish... cabbage rolls...
