Bread, butter, cheese and heat—the grilled cheese sandwich has to be one of the simplest meals around. It’s been a staple of the American diet since Mr Kraft first invented processed cheese back in 1915—millions were served by the armed forces during both world wars and it was a cheap way to feed a family during the Depression (and probably the Great Recession as well). But there’s a world of difference between your run-of-the-mill grilled cheese and a truly great one, especially these days with gourmet and even international versions. Thankfully, the Eastburn Grilled Cheese Invitational is here to find the best example in Portland—nine restaurants will battle it out with the public deciding on the winner (taste, originality and presentation all count). It’s an all-ages event and half the proceeds go to the Portland Women's Crisis Line. And it's tomorrow! Don't miss it.

2nd Annual Grilled Cheese Invitational, Eastburn, 1800 E Burnside, August 29, 5-10 pm, $20 (further information available here)
