Okay, now I have proof. Vegetarians can eat very well in Argentina. There are good salads EVERYWHERE. And then there are also empanadas with cheese and onion, humitas (corn meal tamale with cheese and peppers we got in Salta -- yummmm), omelets (French and Spanish style), mushroom ravioli, butternut squash ravioli, flan, gellato .....

Even Estancia Santa Suzana was able to provide a delicious vegetarian meal (sacrilege, I know).

The only thing we had trouble finding was soup. Argentinian restaurants have very little soup.

Thanks to everyone who answered my questions and provided information. We had a wonderful 3 week trip (Buenos Aires -> Iguazu -> Salta -> Bariloche -> Buenos Aires ->Colonia, Uruguay -> Buenos Aires).
