This lettuce is called Hjertesalat in Norwegian and I believe it is the same lettuce as Little Gem Lettuce in England. Norway produces Hjertesalat from May to October, it is probably in the peak season, I see many fresh Hjertesalat in my store.
If you cut it like this, halved lengthwise, it looks like more Chinese cabbage than lettuce, the leaves are upright. And this lettuce is different from ordinary lettuce as it is super heat-torelant.
So we grill this lettuce on a very very hot grill pan.
The secret is this hot hot grill pan and you cook Little Gem Lettuce very quickly.
I just added some Kosher salt. No oil, no other spices, no nothing.
I think I want the water in the Little Gem Lettuce to boil quickly, so adding any other liquid will only prolong the process. Sometimes the most simple way is the best.
Served on the side of Spicy Grilled Chicken.
You can add Balsamic vinegar or Walnuts oil or good Olive oil on the lettuce right before you serve.
Simple, but very good.
