Prep the romaine hearts: Pull off any old leaves. Chop off the top 1 or 2 inches of the lettuce head, and shave off the browned part of the root end, leaving the root end intact so that the lettuce head stays together.
Prepare your grill: Turn your gas grill to high or get your charcoal coal grill very hot.
Prepare the vinaigrette: Put the oil, vinegar, herbs, salt and pepper in a small bowl and whisk with a fork to combine. Paint the lettuce hearts all over with the vinaigrette.
Grill the lettuce: Grill the romaine hearts until lightly browned on all sides, turning every minute or two until done.
Serve immediately: Serve immediately. You can either serve the hearts whole, or chop them and toss them for a salad. Did you love the recipe? Give us some stars and leave a comment below!
