A while back on the grilling/smoking forums, grilled romaine was popping up as something else to grill. It might have even been mentioned here and met with some skepticism, as who tosses lettuce on a grill?
Well, I do now
The slightly wilted lettuce, coupled with some nice grill marks and grill flavor is good a number of ways; with fresh parm grated on top, chopped up and used in a traditional salad, or sometimes I sauté some onions, garlic and carrots in EVOO and hit it with a little balsamic vinegar for a nice warm salad. A few leaves tossed on the grill also make a nice addition to a BLT.
Cut the romaine in half lengthwise, brush with EVOO if you like (mine always has minced garlic and other seasonings in it), then toss it on the grill for a few minutes. If it's over a flame, you will
have flare ups with the oil, but that's a good thing.
Try it, you might like it.
