Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13 inch baking dish.
Cut Tatume squash in half lengthwise. Scoop out the flesh in the center, leaving about 1/3 inch of the shell. Dice or chop the flesh in a food processor and transfer to a large bowl.
Heat 1 tablespoon olive oil in a large skillet over medium high heat. Add onion and garlic and saute for 2 to 3 minutes. Add jalapeno pepper, serrano pepper, parsley, lemon pepper, oregano, and red pepper flakes; saute for 1 more minute. Add vegetables to diced squash.
Add pork sausage and ground beef to the hot skillet; cook and stir until browned and crumbly, 5 to 7 minutes. Add meat mixture to the vegetable squash mixture. Mix in 1/2 cup Parmesan cheese, bread crumbs, eggs, salt, and pepper until the filling is well combined.
Add remaining 1 tablespoon oil to the skillet. Add diced tomatoes and red pepper sauce. Cook, stirring occasionally, until heated through, 2 to 3 minutes. Season with salt and pepper and remove from the heat.
Pour a ladleful of sauce into the bottom of the prepared baking dish. Fill one squash shell with the filling, making a large mound on top. Place in the baking dish and repeat with remaining squash and filling. Pour remaining sauce into the dish, and sprinkle the stuffed squash with the remaining 1/2 cup Parmesan and mozzarella cheese. Cover with aluminum foil.
Bake in the preheated oven for 30 minutes. Increase oven temperature to 400 degrees F (200 degrees C) and bake until squash is fork tender and cheese is lightly browned, about 10 more minutes.
Garnish with fresh basil and serve.
