El Tesoro right down the street (the big yellow building) has an excellent produce section and meat counter if you eat that as well as plenty of staples. Their prices are also very competitive. Even after moving to Cranston, we still return weekly to pick up things that we'd otherwise need to get by visiting more than one big-box grocery store.

There is also another smaller one on Union that has an entire refrigerated room of produce, similarly well priced and a well-rounded selection.
