Sloppy Joes for 100

Can be made ahead, frozen in freezer baggies, thawed overnight in the refrigerator and reheated.

12 quarts, serves 100 regular eaters. Increase about 1/3 if serving teens only. This recipe fills one electric roaster.

Roaster: Set your electric roaster to 250 degrees, spray the liner with nonstick spray. Remove meat to the roaster with a slotted spoon to a roaster, leaving behind much of the grease. Add the sauce ingredients. Cover and simmer 3-4 hours, stirring occasionally. Turn down to 180 degrees to hold for serving.
Oven: Set oven to 300 degrees, cover pan tightly with lid or foil. Cook 2-3 hours, turn down to 180 degrees to hold for serving.
Serve on buns with condiments on the side (see the
sandwich event page for amounts of condiments).
