You can make a good, hearty pasta sauce...
--1 lb ground beef
--1 sm onion, chopped
--2 t. minced garlic
--2 cans diced tomatoes
--2 cans tomato paste
--1 T. Italian seasoning blend
--1 t. kosher salt
--2 T. sugar or Splenda
Brown beef with onions and garlic. When meat is done, add tomatoes, tomato paste, and spices/sugar. Stir thoroughly and simmer on medium-low heat for at least 15 minutes, stirring occasionally. If you really want a treat, add 1/2 cup light cream or evaporated milk for extra richness. You can also sneak in some extra veggies by adding finely chopped carrots or peppers when you brown the meat.
You can also make kind of a poor-man's stroganoff
--1 lb ground beef
--1 small onion, chopped
--1 t. minced garlic
--fresh or canned mushrooms (optional)
--2 cans cream soup (Use the light version. Any combo of cream of mushroom, celery, or chicken will work.)
--8 oz light sour cream
Brown beef with onions and garlic. Add mushrooms (if using) and cook through. Add soups to the beef, stir to combine, and heat through. Right before serving, add sour cream. Serve with cooked noodles and a vegetable.
