Haven't found what I've been looking for in terms of things to do with saltines, had a friend who did them that way but you could probably use pie crust or phyllo dough for the same sort of result.
Friend would whip egg whites into a meringue, put a fluffy coat on the cracker and then sprinkle with sliced or diced almonds, a zig zag of honey, and a bit of salt on top. Broil for the meringue to toast. You can even use dried egg whites to make meringues, but she had chickens and for most of the year she had plenty of eggs.
