This kind of salad is also really good with poppyseed dressing. There are an infinite number of fruit combos also. I like to add red onion and avocado in addition to fruit--such as honey dew and kiwi, or citrus and avocado. But always red onion.
I'll have to try out the poppyseed dressing... that sounds like it could be a good combination. ...and the kiwi sounds great! ...do you not find the red onion too sharp a flavour for the salad? I guess the only way to find out for myself is to try it =)
