Slice the squash in half lengthwise. Rub the open flesh evenly with 1 tablespoon of the olive oil. Sprinkle evenly with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
Place squash halves, cut sides down, on a baking sheet and bake for 50 minutes. Let the squash stand 10 minutes and then scoop out and discard any seeds. Scrape inside of squash with a fork to remove spaghetti-like strands. Set aside.
Meanwhile, cut the veggies into bite-size chunks and set aside.
3 Cups Kale, 3 Baby Bella Mushrooms
Remove the casings from the sausage and brown, breaking up the meat in a pan over medium high heat. Drain any grease and set aside on a plate.
1 Link Italian Sausage
In the same pan, heat a drizzle of olive oil (about a teaspoon) and sauté the veggies until tender, adding a little salt to taste just before they are done cooking. Adding salt early to mushrooms will draw out the water and they will boil instead of caramelize. Remove from heat, set aside with the sausage. Return the pan to the stove.
3 Tablespoons Olive Oil
Melt the butter over medium heat and let cook until slightly brown, foaming, and fragrant, 2 to 3 minutes.
3 Tablespoons Butter
Add 2 more tablespoons olive oil, thyme, garlic slices and stir to combine for about 1 minute. Add the veggies and sausage back in along with the spaghetti strands and toss to combine. Pile everything back into the squash bowls and top with cheese.
