The Czech language has many words pertaining to food and eating which begin with "ob" e.g.

obalovany meaning breaded
obcerstveni meaning a snack served with drinks
obed meaning lunch
obiad meaning dinner
obilne klicky meaning groats
obloha meaning garnished with vegetables
oblozena masova misa meaning cold cuts
oblozeny chleb meaning sandwich

As I speak/read not one word of Czech, I have no idea what sort of root (no pun intended) makes these words appear related.
