Cucumber salad (sliced cukes, sliced & separated red onion, & bottled Italian dressing -- very quick & easy)
Caprese salad -- sliced tomatoes, fresh mozzarella, basil leaves, drizzled with olive oil & balsamic vinegar
Corn salad -- cooked fresh corn kernels (good use for leftover ears of corn), chopped vidalia onion, chopped green pepper, chopped red pepper, coarse ground black pepper, salt, poppy seed or Vidalia onion salad dressing

I don't measure the stuff, I just chop, drop & taste test.
