Sweet 'n Salty Lemon Dessert

I love  recipes with a 'surprise' ingredient. This recipe  came from a local radio station owner when I put together a community cookbook some years ago. The salty cracker crumbs are a good contrast to the sweet meringue and sweet-tart lemon filling.

Preheat oven to 400. Crush 1/3 box Keebler Club Crackers and save a couple tablespoons for a garnish
Mix with 1 stick melter margarine or butter & spread in a 9 x 13 pan.
Beat 3 egg whites until glossy, add 1 c sugar, and beat til stiff. Spread over the crumbs. Bake for 10 minutes, and cool. Spread  prepared package of ( cook-type) lemon pudding or  1 can lemon pudding/pie filling  over the top, then top that with about 5 oz cool whip or whipped cream. Chill for several hours before cutting in squares to serve, and sprinkle with the salty crumbs and/or a tiny bit of lemon zest..
