Preheat oven to 400º. Place squash cut side down in baking dish and add a little water to dish. (Alternately, can use a lightly sprayed baking sheet and skip the water.) Bake in oven for 30 to 35 minutes.
While squash bakes, make turkey mixture. Pat turkey dry, heat about a tablespoon of olive oil in skillet and when hot, add turkey in one piece. Do not move or break up, let brown for several minutes. Flip and brown other side for a few minutes, then start breaking up with wooden spoon until crumbled and cooked through.
Add onion, garlic and a little salt and pepper. Cook and stir until onions start to soften, 3-5 minutes.
Stir in tomatoes and chilies, cumin, chili powder, smoked paprika and bay leaf. Cover and simmer for about 20 minutes. Taste for salt.
Turn over baked squash and generously fill cavity with turkey mixture. If using, top with a spoonful of homemade red enchilada sauce. Top each with a heaping tablespoon or two of shredded cheese. Return to oven and bake another 5 minutes, until cheese is melted. Enjoy!
