We make a very rich and easy "Rough Puff" Pastry using the Cuisinart and
1 pound of flour
1 pound of unsalted butter
1/2 pound of Brie
(all ingredients used cold)
Buzz it up in the Cuisinart until just before it makes a ball. Let it rest in the fridge for about an hour, and roll out and use.
This should be sturdy enough for what you want, and the cheesy crust will add (only) a subtle depth of flavor. It won't compete.
