Sorbet! You can make a beautiful mold -- egg-shaped, lamb, whatever -- with different colors of fresh fruit- and herb-flavored sorbets, and garnish with fruit and more of the same herbs. No lactose, no fat. :lips: And you can always have whipped cream on the side for those who can. :D
And the best thing is that you can make it ahead of time, in fact you have to, so you won't be fussing, away from your guests. You can either make the sorbets yourself, or buy good ones. Either way, it will work.
