This is my old tried and true which is always demanded at pot lucks:
Killer salad:
a bag or box of spring greens (romaine and spinach work too)
grapefruit and orange sections
strawberries and any other berries you want
maple walnuts or pecans or candied in some way
gorganzola cheese crumbles
raspberry vinagret dressing (go easy with it, the salad has enough going on)
easy breezy and always gets the raves.
