I have fond memories of our cafeteria food in school as a child and one of my favorite meals was the spaghetti and garlic bread. Probably because it reminded me of home and I'd rather be there than school. lol
Brown ground beef. Drain fat; add onions, spaghetti sauce mix, pepper, oregano and garlic. Stir in tomato sauce, chicken base, Worcestershire, sugar and salt. Bring to a boil; reduce heat and simmer 45 minutes. If sauce needs thickening, dissolve a little cornstarch in hot water and add to sauce.
Meanwhile cook spaghetti. Drain, but do not rinse. Stir cheese into sauce to melt, then stir in spaghetti. Transfer pasta and sauce to a baking pan and cover with foil. Place in a 225 degree oven for 1 hour.
