Salad for a large crowd

We make a grain salad (actually we use Trader Joe's grain mix which includes the larger pearl couscous, baby chickpeas, and seeds, but you could use any grainy mix), olive oil, sun-dried tomato slivers (also from Trader Joe's), lemon juice, salt, minced scallion, and any minced tender fresh green herb (parsley or basil, for example).

Thanks, everyone! All great ideas. So hard to pick...

How could I have forgotten this recipe? It is delicious! https://food52.com/recipes/12928-dilled-crunchy-sweet-corn-salad-with-buttermilk-dressing

Love this recipe because it can be refrigerated over night for better flavor.

For a large crowd I'm thinking of something sturdy. There are many variations of broccoli with sunflower seeds, raisins and a ranch style dressing.

There's a recipe in Ottolenghi's Plenty for a salad of thinly slivered cabbage and kohlrabi with dill and dried sour cherries in a lemony dressing. It is much more than the sum of its parts. Here it is on a blog: https://www.everopensauce.com/cabbage-and-kohlrabi-salad/
Just noticed it had alfalfa sprouts in it too -- I don't really like them and have never included them. I also imagine they wouldn't hold up well, but the rest of the salad does. I think it's even good the next day.

Couscous with harissa, lemon preserves, roasted carrots, mint/parsley topped with feta.

Charlie Bird restaurant in NYC has a great farro salad that will hold up nicely (add cheese and arugula before serving though) Recipe is available online

Thanks everyone! Will test drive a couple of these ahead of time.

1. Zucchini, tomato and onion with Italian dressing.
2. Red cabbage, celery, red onion with an apple cider vinegar dressing
3. Green beans, slivered almonds, mushrooms
4. I love green pea salad! Peas , onion, bacon bits with a mayo dressing.
5. Festive salad with seasonal vegetables. Corn, beans, red cabbage, tomatoes, radishes, parsley, carrots, colorful and fun!

Depending on what else you're serving and what your guests eat, 2 ideas:
Seasonal and rich (pears, walnuts, some good blue cheese and a white wine vinaigrette)
Pretty and tasty: roasted carrot salad with avocado, sprouts and a cumin dressing (by Vongerichten at his restaurant in ABC Carpet, now everywhere)
