In an enameled cast iron pot on medium heat, brown the ground beef, salt, pepper and olive oil.
Add the onion, oregano, thyme and garlic and sweat until translucent. Add the Italian seasoning and mix together, seasoning with another pinch of salt.
Add the crushed and strained tomatoes, bring to a simmer, reduce heat and cover for 30 minutes. Stir occasionally.
While that cooks, make your noodles (or cook your spaghetti squash - whichever you use) and serve when ready.
