While the squash is baking, put on a pot of rice. You’ll only need a heaping ½ cup of cooked rice for this recipe, but I usually make a whole 2 cups and save the remainder for another recipe, maybe Spanish rice or a warm rice salad with walnuts, cranberries, kale and feta in a light vinaigrette. I used white rice because that’s what I had but wild rice would be even better, or you could try red rice, quinoa or couscous.
While the squash is baking, you might want to reach in and poke it a couple times to make sure it’s not getting too soft or to make sure the skin isn’t burning. The cooking time may vary because every squash is a different shape and size. It should hold its shape when you pick it up (with oven mitts, of course). Allow it to cool for maybe 20 minutes or half an hour. It doesn’t have to be room temperature, but it does need to be cool enough to handle. When the squash is comfortable enough to touch, pop the little stub of a stem off and slice it right down the middle lengthwise. Next, scoop out the seeds and discard them. Then scoop out the flesh and put it in a bowl, leaving a ½ inch border around the outside to help the squash hold its shape and cradle the fillings.
Remove five slices of turkey bacon from the package and cook them however you like them, in a pan or in the oven. I put mine in a 350-degree oven and baked them until hot and cooked through but not crisp. Pork bacon is just fine, and you might be tempted to use more than five slices, but you don’t want to let bacon overwhelm the other flavors. For a vegetarian filling, omit the bacon altogether and double the mushrooms.
While the bacon is cooking, slice up a whole small-to-medium onion and saute it with a generous tablespoon of olive oil, 1/8 teaspoon salt or salt to taste (keeping in mind that you’ll be adding other salty ingredients), a couple dashes of lemon pepper and five fresh sage leaves, chopped fine. I was feeling quite contrary when I was cooking this and so I also added a dash of cayenne pepper, even though my husband dislikes the heat. If you like the heat, add three dashes. Five dashes will likely render you senseless, but you do you. Let the onions get quite soft, adding more oil if necessary. If you have fresh mushrooms, that’s excellent, but I didn’t so I added a 4-ounce can of mushrooms, plus the liquid. Let everything simmer together until the liquid has cooked off and the onions are just starting to caramelize.
