In a martini glass or sundae dish, layer the sorbet and gelato scoops. Drizzle the lemon curd over the top.
Crumble the cookies over the ice cream. Top with the whipped cream. Serve immediately.
Notes
Stock up on ingredients when they are on sale. The holidays are a great time to stock up on baking ingredients. You may even find meringue cookies on clearance. Ice cream tend to go on sale fairly often; I usually buy several flavors at one time and stash them in the freezer.
Bake your own cookies. Meringues take basically eggs and sugar. Likely, they're cheaper to bake at home.
Note: it was incredibly difficult for me to find Lemon Sorbet. I only found one brand in one store. I don't know if that's a regional thing, but snatch up whatever you find. You could also substitute another citrus sorbet for a similar flavor.
