Now this was a great meal.  I don't know if the culinary experts will scorn at serving halibut with a sweet spinach salad dressing, but if they do they are wrong.

Step 1, get the squash going.

1 Delicata Squash.
1 tsp butter
salt, pepper

Bake the squash in a 350 oven for about 25 minutes upside down.  Tin foil is your friend.  Flip, and bake another 15 or so, depending on size.  Let cool a bit, scrape out the innards, stir in the butter, and season with salt and pepper.  Done.

Step 2, the spinach salad.

1 Bunch spinach (of course)
For the dressing I went to my old standby for this.  It's never failed me.  Nancy's Spinach Salad. Courtesy of the Food Network.  I skip all of the eggs, mushrooms..etc and just use the basic dressing.  Personal decision based on my mood.

Step 3, the halibut.

First, I put some kale into a hot pan with oil, 1 clove of smashed garlic, and a splash of lemon juice.  Added about 1/2 cup water and covered for 5 minutes.  Probably overkill as I then add the halibut on top of this. 
The halibut was coated lightly in olive oil and seasoned with salt and pepper.  Cooked covered on top of the kale for 6 minutes, flipped and cooked again for about 2.   I finished it off under the broiler (here, using oven-safe pans really comes in handy).  The end result:
