Here's a super weeknight dinner the whole family will love—and it’s ready in just 30 minutes. Thinly slicing the chicken will ensure it cooks quickly and evenly. Covering the pan when the broccoli cooks helps build up steam, bathing the florets in heat and cooking the tops that aren’t in contact with the hot pan. You’ll need 1 small to medium head of broccoli to produce enough florets and 1 lemon to yield enough zest and juice for this entrée. Round out the meal with a side of angel hair pasta, rice, or couscous to soak up the sauce.
