Is there any way to make jack-o-lantern pumpkins worth eating? Background: For the holiday Halloween in America, we make decorative lanterns -- Jack'o'Lanterns -- from large pumpkins.  These pumpkins are bred to be large, durable, and dry to make them easy to carve.  This also results in them being fairly mealy and tasteless as food.

Question: is there any food preparation I could make with a surplus jack'o'lantern pumpkin that wouldn't be a waste of the other ingredients?  Some way to prepare it that would make up for its dry texture and weak flavor?

I've tried roasting one (Afgan-style) on previous years, and it didn't help; it was dry, mealy, and roasted. And yes, I do clean and toast the seeds, which are tasty.  I'm looking to do something with the flesh.
Admittedly our carving pumpkins in the UK are smaller than yours, which may affect the texture, but this year and last I made:


three been and pumpkin chilli
pumpkin tagine
pumpkin spice cupcakes
pumpkin curry 
pumpkin, pepper and mushroom fajitas


All of these get most of their flavour from other ingredients. All were successful. 

The chilli, curry, and tagine all start by frying the diced/roughly chopped pumpkin until nicely browned with tasty ingredients (spices, onions, and plenty of garlic), before quite long simmering. The curry was last year but I think I went for quite hot, with a sauce based on tomato, coconut, and mango (I certainly did when I made it again this year).  The fajitas were cut into strips and fried, just like the other veg, though I did the pumpkin first and reserved it, to be sure it was cooked through.  Again, plenty of spices, garlic etc.

The cupcakes (for which there are plenty of recipes online) started by microwaving and pureeing, and ended up similar to carrot cake - moist and popular. I added latte buttercream.
