Recipes with few ingredients

FerociousKoala

I'm currently living temporarily in another country, so I don't want to build up a lot of groceries as I would have in my kitchen at home. I would appreciate any recipes that are low calorie and healthy that have few ingredients!
I typically have a lot of produce and some spices on hand. Sometimes I have milk if I think I'll be able to use it all before it goes bad (it's expensive here). Always have butter and bread. Usually have eggs, too. Just to give an idea of the things I fill my cabinets with!
I especially am craving soup, but have no chicken/veg stock and no flour! Any help there as well?

Thanks in advance
