Macaroni & Cheese soup
2/3 cup bacon bits ( I used the fully cooked) precrumbles but you can also chop up 5 slices and fry them up and use the bacon fat to saute the vegetables
1 onion, minced fine,
1/4 cup each celery & carrot minced fine
1 T. Worchester sauce
2 T. bacon fat
1 can chicken broth
1 1/2 cups macaroni ,dry
4 cups milk
seasonings of your choice here's what I used :
1/2 tsp each; dry mustard, paprika, onion powder, chili powder
1/4 tsp parsley flakes, black pepper & nutmeg
1/4 flour
1 8 oz block grated co-jack cheese
1 8 oz block grated mild cheddar cheese (save 1/3 cup shredded cheese for top of done soup)
3 chicken buillon cubes
1 T. cornstarch
1 T. water

In large pan place water and buillon cubes bring to boil and cook pasta as directed on package.  While that cooks, in soup pot place bacon fat, melt add onion, celery & carrots and salt & pepper to taste.  Saute until veggies are tender add garlic and cook for about a minute or until fragrant.  Deglaze the pan with worchester sauce, sprinkle flour over mixture stirring for a couple of minutes add chicken stock and seasonings.  Whisk constantly or until mixture comes to a boil.  Drain pasta . Add rest of the ingredients to the pan mixing well.  Keep stirring until cheese melts and mixture is boiling.  In small bowl mix cornstarch and water.  Add to soup mixing well bring soup up to boil and cook until slightly thickened.  Serve soup in bowl and add a little remaining shredded cheese to top of bowl.
