In the past, we've roasted the seeds. Carving pumpkins were bred to be big, not to be tasty. So if you want a good eating pumpking, you're better off with a pie pumpkin.
I made a black-bean pumpkin soup. To be honest, I didn't care for it, but I don't much like pumpkin. It got a lot of rave reviews. Don't have the specific recipe, but you get lots of hits from Google.
I have used both sweet potato and butternut squash, but some reviewers mentioned using pumpkin and liking it.
Something else I liked a lot was a stuffed acorn squash. You brown up some ground beef and some onion and seasonings, cooking some rice, stuff the acorn squash and bake. It would probably be yummy in a small pumpkin as well.
I used this as the basis for my recipe for cheesy bean bread. Not sure if you're doing low carb.
Something else I did that was yummy was a pumpkin roll up. I don't have the specific recipe, but you can google. You bake a thin pumpkin cake. The texture is similar to a pancake. You make a frosting with cream cheese, then you spread it on the cake and roll the cake.
I made grilled okra a few weeks ago. It was great! I had never made it before, so I only made a small amount. We were having dinner guests, and I put 1 okra on each plate and told them, "This is a new recipe. If you don't like it, that's fine!" We gobbled them down like popcorn.
Our pumpkins are slightly different than yours, but I make pumpkin pie and this year I'm going to try a new recipe to make pumpkin cake :D
Also my mom and MIL make dulce de calabaza (pumpkin candy) and DH loves it, I never cared for it, but might do that as well.
I didn't have any yogurt, so I didn't do the sauce, but I bet it would be fabulous! I just tossed the okra (whole, no chopping!) in veggie oil (not olive, it burns too easily), salt, pepper and a squirt of lemon juice. Skewer and grill for about 3 minutes per side, until tender.
