What is a latke? A giant potato pancake! But, the real question here is why aren’t latkes a dinnertime staple? They’re crunchy, salty, and can be a vehicle for any number of toppings—in this case, roasted shiitakes and mustard greens. Instead of doing the hard work of grating potatoes, ready-to-go frozen hash browns do the heavy lifting, leaving you time (and energy) to roast the greens and mushrooms. Add a dollop of creamy sour cream and you’ve got a seriously satisfying vegetarian dinner.
