ahh, summer. the season that's synonymous with things like sun, citrus, vacay, (most recently, yes way rosé) and most of all, grilling. it's an activity that brings everyone together, because, let's face it--we all love food. even if you don't know how to grill, have no fear. there are many ways to achieve summer superstar status with this no-frills flank steak and (very easy) blackberry chimichurri, that can virtually work on any type of grill or grill pan that can achieve high heat.
