LeAnn's Famous Sloppy Joes

These are a Halloween tradition ever since my Tyson married his beautiful wife Brandi.  Every year at Halloween we are invited to Brandi's parents house LeAnn and Bill for some DELICIOUS sloppy joes.  This year we had our own Halloween and I figured we would carry on the tradition.  Since these are no manwitch sloppy joes, it was a rather easy choice.  Leann also graciously gave me the recipe so I was very excited to try them!!!

4 lbs ground beef (I substituted one pound for ground turkey and didn't think any flavor was sacrificed)
1 qt (32 fluid oz) ketchup
2 tsp lemon juice
1 c chopped celery
1/2 tbsp ground pepper
1 large chopped onion
1/4 c vinegar
salt to taste
1 1/2 tsp Worcestershire sauce
1/4 c brown sugar
1/2 c water
1/4 c tomato paste
1 tsp water
1 tsp mustard
1 c grated carrots
1 small can El Pato tomato sauce (found in Mexican Food isle)
Hamburger buns
Sliced cheddar cheese

Brown, season and drain hamburger in a large skillet.  In a crockpot, add cooked hanburger and the remaining ingredients through tomato sauce.  Simmer on high heat until the celery, onion, and carrots are tender, about 4 hours.  Serve over hambuger buns, and top with sliced cheese.
