Inspired by an omelette brunch special offered offer by Johnny D's in Davis Sq, Cambridge, MA. The ingredients sounded awesome, I just wasn't so sure about them being in an omelette, so wrote down the ingredients and tried making a salad out of them. Turned out well! Restaurant actually used white beans, not butter beans, but 1) couldn't find white beans at the market the day I made this, and 2) I *love* butter beans. But use whatever you like best!
