You eat this Spaghetti Pizza just like you would a pizza… picking up the slice with your hand and taking a giant bite!
Bring a large pot of salted water to a boil. Add noodles and cook to package instructions.
Combine ground beef, onion, garlic, green pepper, salt and pepper in a large saucepan. Cook and stir until meat is brown and vegetables are tender. Drain grease.
Stir diced tomatoes, tomato sauce, and tomato paste into the pan. Season with oregano and basil. Simmer spaghetti sauce for 20 minutes to 1 hour, stirring occasionally.
Remove the Focaccia Crust from the oven and top with cooked noodles and spaghetti sauce. Slice and serve.
