Chop and squash in half and scrape seeds out.  Line a cookie sheet with aluminum foil.  Season spaghetti squash with olive oil, salt, and pepper.  Place flesh side down and roast for 30 to 40 minutes until fully cooked.  Remove from the oven and let rest until cool enough to handle.

Chop onions and cook them until tender, add garlic and fake or real ground beef.  In another pan cook mushrooms in butter.  Add zucchini to the meat pan until cooked.  Add marinara sauce, el pato sauce and mushrooms.  Let simmer.

Remove cooked squash from shell with a fork.  It should come off easily and should look stringy, like angel hair pasta.  Top squash layer with marinara sauce layer.  Top with mozzarella cheese.
