I got this from another blog recipe site and it looked good and easy!
2 pounds sliced deli ham
1 C. Water
1 C. Ketchup
1/4 C. Brown Sugar
1/4 C. Worcestershire Sauce
2 Tbs. White Vinegar
2 tsp. Mustard
A few shakes of salt & pepper to taste
Hamburger Buns~~I used Kaiser Rolls
Split & toasted.
Grease crock-pot and place Ham inside. Combine remaining ingredients in a separate bowl. Wisk together until well combined. Pour over ham and mix well. Cook on low for 4-5 hours or until heated through. Stirring occasionally to keep ham moist. Serve on toasted buns.
