Russian Food Ideas?

Next week is "Russia Week", and it's been hot. I don't want to bake or make soups. What to feed my children that is Russian....

I am planning to make blinis with cream cheese and smoked salmon atop. (Knowing my children, I won't even waste money on caviar!) I've got apricot jam and pickled vegetable jars to crack open, although I know my children won't be too interested in the beets. I know they'll eat eggs, cucumbers, bread, cheese, tomatoes, potatoes, and pirogi, so I guess that's what we'll be eating for most of the next week. I hope I can find some berries on sale somewhere. For herbs, time to use up the cilantro in the fridge and find some dill weed instead. And for drinks, vodka is totally out, but I bet my children will enjoy some sweetened, iced herbal tea.

Any suggestions from readers as to what to eat that is typically Russian on a hot summer's day? (In a house with no AC running?)
