Place all Meatloaf ingredients, except ground beef, into a large bowl and mix well. Add in the ground beef, then shape into a ball.
Line crock pot with tin foil and coat with cooking spray. {This not only makes clean up easier, but it helps to lift the loaf out of the pot for easier slicing!}
Place meatloaf onto the foil in crock pot, cover and cook on low for 3-4 hours until no pink remains {if you'r using a thermometer, the temp should reach 160 degrees F.}
Combine sauce ingredients and pour over meatloaf for the last hour of cooking.
When meatloaf has finished cooking, let stand for 10 minutes, then remove to slice if desired.
