Use as you would any lettuce:
-low carb, gluten free wrapper. think Asian and use the lettuce to wrap grilled meats or tofu, with some grated carrots, bean sprouts, mint leaves, cilantro, etc. Dip your wrap/roll in a peanut sauce or sweet chili sauce, etc. Like Vietnamese summer rolls, lettuce 'cups', burritos
- as lettuce in sandwiches
- noodle salad bowls
I don't recommend any heating because the red lettuce isn't usually very sturdy and will wilt to nothing. And the beautiful color turns brownish and unappetizing.
There are a lot of ideas for using an overload of lettuce in this thread: https://food52.com/hotline...
Liz the Chef, a regular here on Food52 and she also has a great blog just posted a recipe that sounds amazing for red lettuce soup. Here is the link to her blog http://lizthechef.com/

I was also going to suggest Kukla's Shalotta recipe. So different, so delicious!
I get loads of leaf lettuce in my CSA, as well, and after so many salads/sandwiches, I clued in that it was amazing cooked, too. Use it like you would other greens -- it is delicious in stir fry.
