Preheat oven to 375°F.

Halve squash lengthwise and use a spoon to scoop out seeds and discard.

Place squash cut-side down in a 9x13-inch baking dish.

Pour 1 cup water into the dish and roast until squash shells are tender when pressed with your finger, about 30 minutes. Let sit until cool enough to handle. Leave oven on.

Meanwhile, pour tomatoes into a strainer set over a bowl.

Set tomatoes aside and pour juice into a blender.

Add almond butter, curry powder and 1/4 teaspoon of the salt and blend until smooth.

Rake a fork back and forth across squash to remove flesh in strands, keeping shells intact.

Return shells cut-side up to the baking dish.

Spoon one-third of the squash in shells, dividing evenly.

Top with half of the tomatoes and half of the greens, then drizzle with about one-third of the almond sauce.

Repeat the layering, then top with remaining squash and sauce.

Roast until filling is heated through and greens have wilted, about 15 minutes.
