I didn't find the food in Uzbekistan anything to write home about .... but alas, here I am kind of writing home about it ;)  My favorite meal was breakfast and often filled up on as much as possible since it was included in the price of the hostel and that way I didn't have to buy lunch :)  

Typical breakfast offerings:

Eggs (fried or boiled) but not always eggs.  A kind of rice porridge with milk, maybe yogurt, Uzbek flatbread (good when it's fresh - gets stale quickly), jam, fresh fruit (grapes, figs, plums, tons of watermelon and really good honeydew), a pot of either green or black tea (or instant coffee), maybe fried potato, maybe a baked quiche kind of thing.... these were kind of one -off things that different guest houses had.  Overall the breakfast is quite filling and will satisfy you easily into late afternoon - maybe to dinner.

Lunch / dinner - meat, meat, meat.  Kebabs - or shashlik - are everywhere. Sometimes they are the only thing on the menu, so get used to lots of meat.  They cook them on these little open flame grills on skewers that they lay the metal part across the "box" where the coals are in.  It does have a nice smokey flavor but once you've had it 3 meals in a row you are ready for something else.  Everyone else seems to really like plov (rice pilaf with carrots, meats, etc... you can certainly find a better description elsewhere for this) - but I found that the heavy hand on the cooking oil upset my stomach.  Nontetheless, it's a must try once at least. You will occasionally find variations on these themes as well... different kinds of rice dishes, or different barbecued meats. I had some nice lamb chops (always served with onions) in Samarkand.  There's also always a take on a greek salad, minus the feta, and plus a heavy hand of dill.  There's also another dish with an unfortunate translation....Jiz.  Kind of a meat stew.  And then that's about it.  My experience was that most restaurants had about half of the items on their menu. I didn't eat many desserts since everyday I was having a coke; at least one if not two because it was so bloody hot.  They have soft serve ice cream (or "product") on every street corner for really cheap; so I would grab a cone every once in a while.  In the end, I was pretty tired of Uzbek food after 10 days.
