Spaghetti sauce with Negra Modelo

I've made this sauce, which is similar to Bolonaise, except I use beer. It tastes pretty good and is easy to make! Make sure you use natural or organic beef! You will be amazed by the quality of the meat!

Serves four hungry people

Ingredients:

1  Tablespoon olive or canola oil
1/4  Cup finely chopped organic celery, ribs and leaves (optional)
1     Small Package organic white mushrooms, finely chopped
1/4  Cup finely chopped organic carrots  
1/4  Cup finely chopped organic yellow or white onion
3 to 4  Cloves organic garlic
1  lb.  Natural or organic beef (can be purchased at WalMart or one of the Coop's)
1 Teaspoon organic oregano
2  14.5 Oz. cans organic diced tomatoes ( I use Muir Glen Organic)
1  Heaping Tablespoon of organic tomato paste (Muir Glen)
1  14.5 Oz. can of organic tomato sauce (Muir Glen)
1/2 to 1 whole bottle of Negra Modelo beer (depending on how thick you want the sauce)
Salt and pepper to taste.

Heat oil in large pot over medium heat. Add carrots, onions, garlic, and celery to hot oil. Saute until vegetables are soft and onions and garlic are lightly browned. Sprinkle with salt while sauteing. Add mushrooms. Saute until cooked. Stir frequently to avoid burning. When everything is lightly browned, scrape vegetables out of pot and place in a glass bowl. Add ground beef, breaking it up with your hands as you add it to the pot. Cook beef until lightly browned and lightly sprinkle with salt and pepper. Add oregano. Return vegetables to the pot. Mix all ingredients together. Add cans of diced tomatoes, mix everything together. Add tomato paste, mix thoroughly. Add tomato sauce and keep on stirring! Add Negra Modelo. Turn up heat on pot until the sauce starts to boil. Stir frequently for a few minutes. Turn heat down and simmer for one hour with a lid on the pot, stirring occasionally. Serve with cooked spaghetti and garlic bread!
