Preheat oven to 425 degrees. Cut the acorn squash in half (be careful, and use a sharp knife) and scrape out the seeds. Brush a baking dish and both halves of the squash with olive oil. Sprinkle with a pinch of salt and fresh ground pepper. Place them rind side down in the dish and bake at 425 for 30-40 minutes, til flesh is tender. Meanwhile, heat 1 tbsp olive oil in a skillet or other high-walled pan (I use a Le Creuset dutch oven). Halve and slice the sausages and toss them into the hot oil. Saute the sausage for a few minutes, stirring often, until browned. Remove with a slotted spoon and set aside. Add a little more oil to the pan if needed, and add the asparagus and peppers. Stir fry for a moment and then add a splash of water to deglaze the pan and get all the yummy brown bits from the sausage incorporated. Add a generous pinch of salt, the curry powder, and arrowroot powder and stir til combined. You should get a gravy-like coating on the veggies. If it’s too watery, let it thicken for a bit but keep stirring so it doesn’t burn. Lower heat to medium-low and add the chopped mushrooms and the cooked sausage. Stir well to combine. Once the mushrooms soften a bit, put the lid on the pot and turn the heat off. Give it a taste – since the Jamaican curry is mild, you can add a few dashes of red pepper flakes for some heat if you want (I did). Once the squash is finished cooking, fill each half with the sausage mixture and squeeze fresh lime juice over the top.
