Preferably something healthy but still kid friendly.
Grill fresh corn; let it cool. Add chopped zucchini, diced red onion, jalapeño or Fresno chiles (or bell peppers for no heat), halved cherry or grape tomatoes, lots of drag cilantro and parsley. Make a vinaigrette w fresh lime juice, Dijon, and your favorite oil - season dressing with a little garlic, plenty of ground cumin and coriander. Delicious summer salad!
How about elites (Mexican style street corn)? I also love a good Cole slaw! Good luck, have fun, and Happy Fourth ;)
That's supposed to say ELOTES btw :-)
A French or German style potato salad. Vinagrette, not mayo; keeps well for travel. Can add bacon or haricots vert if you are up for it.
This was going to be my suggestion, too - I've made this recipe for multiple cookouts and Thanksgivings and always get compliments: http://www.epicurious.com...
Ina Garten has a corn salad that I have made many times and it is seriously delicious and it is quick and easy:
We're bringing a Black Bean and Corn Salad. Tonight the beans soak..tomorrow they get cooked with hamhocks.
Then corn is grilled and added to the cooked black beans with red onions, red bell pepper, and hot pepper.
And the salad is dressed with a lime, chili powder, garlic, olive oil dressing and left overnight. Add some Mexican crumbling cheese (or feta) and parsley before serving.
For a crowd avoid cilantro...or serve a bit on the side for people that like it.
