Broccoli salad suggestions needed

[RealLifeMama]

I want to make a broccoli salad that is like traditional broccoli salad w/ the sweet mayo dressing and bacon, but I don't want to use bacon, nor do I want to use sugary mayonaisse dressing, LOL.
I was thinking of maybe using yogurt or a buttermilk dressing instead, but I don't know how to make it sweeter.
Does anyone have a recipe or maybe some suggestions?
I will probably add red onion, raisins, sunflower seeds, cheddar cheese, but am not sure what to dress it with.

Thanks for any suggestions.

Can you cut the mayo down and sub some fat-free sour cream? Maybe add stevia instead of sugar? I think the yougurt and buttermilk would work too, though Hmmmm. Still thinking. :)
