Introducing The Weird Food Column–a weekly column dedicated to all things edible, odd, unusual, strange, wacky, and/or slightly tacky. The more mainstream, the better. Have any suggestions? Leave them in the comments section.The Eruption: Dormant on the plate, not in your colon. This week’s weird food comes from West Seattle’s Heartland Cafe, where folks come for the comfort food (i.e., loaded tater tots) and stay to wait out the heartburn. Case in point: The Eruption ($14). This plate of “What the hell is that?” is built on a half-pound beef patty covered with a mountain of mashed potatoes, green-bean casserole, molten cheddar cheese, and spewing flames of French-fried onions. The Cafe has a watered-down version of this dish called the Volcano ($10), served without the cheese or meat. But really, the huge hamburger patty is what makes this dish work. It’s the structure of an otherwise boring plate of mashed potatoes.The Eruption is salty, creamy, and crunchy in all the right places. The name is also ironic.
