Spaghetti Squash
I buy it and put it in a 400 degree oven whole on a baking sheet. I can't cut it in half raw without nearly cutting my hand off.
I cook for about 20-30 minutes until it's soft enough to easily cut in half. I cut lengthwise, scoop out the seeds and stringy stuff, then place cut side down on a baking sheet or pyrex dish and cut a pat or two of butter under it in the cavity, then after about 20 more minutes or so, it's easy to scoop all the flesh out (it'll turn a darker color and won't be really crunchy anymore).
If I feel fancy, I'll schoop everything out in a pyrex/casserole dish, add cheese and butter and herbs and then bake it again to melt everything together, but it usually doesn't need all that attention.
Wish I could tell you which herbs, but I'm lazy and use herb mixes. I like the mccormick "perfect pinch" ones. I use regular and garlic + herb all the time. They are very balanced so I feel like I can add a lot without overpowering my dish (which happens when I add my own herbs).
Parmesan cheese makes it wonderful too.
I love spaghetti squash, cut in half, scoop out seed, place in a plate in the microwave cut side up and cook on high for 20 minutes. Use a fork to scoop out. Its great as an alternative to pasta and I also love it with butter, garlic and basil as a side dish. A friend just did one the other night - stuffed with all kinds of veggies and cheese - baked in the oven. Yummy
