I have fond memories of our cafeteria food in school as a child and one of my favorite meals was the spaghetti. My great grand-mother was a cafeteria cook for 40 years and unfortunately I never got to twist her ear for some of the recipes. This is my rendition of my school's spaghetti. I know a lot of us loved school lunch and then there are some who still have nightmare's, lol. Give this a shot. I think you will be pleasantly surprised.
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.
