In a pan on medium heat, add olive oil.
Once heated, add your ground beef, giving a quick stir to mix in with the olive oil, then allow to fry untouched for a minute or so.
Once beginning to brown, stir meat, and add in your onion, zucchini, carrots and tomatoes.
Allow the vegetables to cook about five minutes, until onions begin to turn translucent.
Add in your red wine (optional), and cook for about 2 minutes until alcohol has burned off.
Add in your tomato sauce, stirring and allowing to simmer for about 10-15 minutes.
As sauce is simmering, add basil, salt & pepper to taste.
While meat sauce is simmering, preheat your oven to 400F, and slice your squash in half, removing the seeds.
Once sauce is ready, add a sprinkle of salt & pepper to each squash half and fill with meat sauce, top with cheese and bake for 20-30 minutes.
Serve and enjoy!
