Grilled Romaine Hearts | I’ll be the first person to admit that “Lettuce” isn’t the sexiest word out there. A vegetable that’s green. And full of water. Where do I get some of that?! But luckily there is always one good egg in the family, and for the Lettuce family, that would be Romaine. This guy is tall, sturdy, handsome, and best of all, can handle the heat in the kitchen!
