Ideally, it would use matzo but not nuts.

I've made this recipe for Passover and have used matzo in place of saltines for the crust:
I have used macaroons (just cheap canned ones, honestly) smushed into a tart crust, and that has been very successful. I have also made tart crusts out of melted butter (or margarine for pareve), matzo meal, a bit of sugar and some ground almonds. You could leave out the nuts. You could also use Passover cookies, and make the equivalent of a graham cracker crust.
