Pie-love,
I wish I could take credit for it, but it's an idea I'd come across about a year and a half go that was in DESSERTS MAGAZINE. Truly one of those "DOH! I wish *I'd* thought of that!" things. I'm a sucker for things on sticks.
Pardon the pun.
I used 6" cardboard lollipop sticks (obviously, don't use the plastic ones, since they go IN the oven) from Wilton.

These were fun to make and freeze nicely. I made extra (unbaked), froze them on a baking sheet first and then put them in a large Ziploc freezer bag, so now I can make one or two at a time in the toaster oven when I get a hankerin'. (Obviously, just remember to wrap the sticks in aluminum foil before baking to keep them from burning.)
I used a 1-7/8" biscuit cutter for the pies and baked them on a baking sheet lined with a Silpat. Roll the dough pretty thin (no more than 1/8") so you don't end up with JUST a big mouthful of crust. Bake as you would any other fruit-filled pie, using your crust and filling of choice and take care to get a GOOD seal/crimp on them, especially around the stick part. They won't need to bake as long (again, obviously)...just go until you see them getting a nice, golden color on the crust. I imagine, you could also fry these, but I haven't tried that yet.
Your sweet potato pie looks LOVELY!

Joelf - I hadn't even thought about filling them with meat, but that makes a lotta sense. A couple of those, a couple of these and you have a fun little take-to-school-or-work lunch!
