Grilled chicken is totally ubiquitous - it's on every menu and it's usually no big whoop. In fact, it's often boring. But this chicken is SOOOOO worth getting excited about! It's slathered in mustard, lemon, rosemary, and spicy crushed red pepper so it just titillates you palate with flavor. Then it's grilled until the outside is tangy, crusty, and crispy while the inside stays nice and moist. To make this as super-secy as possible, it's served with a perfectly charred and caramelized lemon half for an extra squeeze of flavor.
