Make wraps lettuce, mango, chicken or flank steak, bean sprouts and ginger dressing.

This is also a little off the beaten path:

I also used to love the salad at Austin Grill that had pumpkin seeds but they haven't served it in a while.

Try serving a pasta salad (pasta, peppers, artichokes, olives, parm or feta, oil/vinegar dressing and if you're indulgent whisk in some mayo and lots of basil) on top of a bed of lettuce with crusty bread.

Or make a chicken salad with grapes and celery and green onions and mayo/sour cream/curry and serve it on top of a lot of lettuce with fruit and bread on the side.

As a PP said, make taco fixings but instead of hard or soft shells, serve on lettuce as a taco salad and have chips on the side for crunch and scooping.

When I have a ton of lettuce I often make a small pasta salad (like the one above, or just a plain old mixed frozen veggies + italian dressing with pasta) and/or couscous dish, and serve those with lettuce all mixed up for a more filling and exciting salad. Love this with buttery croutons and vinegary dressing!

I regularly grill my romaine lettuce for Caesar salads - delish.. I think you could do the same and then put some parmesan on top, some croutons and a garlicy dressing.

Also love orange, beet, candied walnut and goat cheese - dress with a balsamic vinegar type dressing - yummy!

My new favorite salad:
Lettuce
Orange segments (fresh)
Avocado chunks
Red beets * already cooked. (produce aisle in the fridge.)
Handful of sweetened walnuts.

I haven't tried this yet, but I've read recently that you can grill it. I think you then serve it like a wilted green side dish, not a salad. Makes me think with maybe a garlicky creamy savory dressing.

How about adding fruit? Strawberries, walnuts and goat cheese

Apple, walnut, celery, blue cheese, honey mustard vinagrette

Asian: carrot, cucumber, wonton strips and sesame dressing

Mexican: cheddar cheese, lime, tomato, sour cream

Or how about making tacos or lettuce wraps?

You can make tacos without the shell and use the lettuce as wraps instead. Or asian-style lettuce wraps.

Or you can do a totally different salad--roasted beets, sugared pecans, goat or blue cheese with the lettuce (although I usually spinach for this one, but you can use whatever lettuce you want).

We have an excess of green leaf lettuce right from our CSA and I am getting tired of my usual salad. Normally I add cucumbers, tomato, avocado and carrots, maybe some radishes and then top with a balsamic vinaigrette. Sometimes I'll add a protein and make it our entree. I need to mix it up. What are your good go to ideas for green leaf lettuce?
