I use this oldie but goodie for small or large groups. If you like it less spicy only use 1 tsp chili powder. I put the amounts for 38 servings in () this fits in a Nesco.
1 LB ground beef (13 Lbs)
1/2 Cup chopped onion (3 cups)
1/2 cup chopped celery (2 1/2 cups)
1/4 cup chopped bell peppers (2 1/2 cups)
1/2 of a 7 oz bottle of catsup (#6 - 20 oz or #4- 32 oz)
2 Tbls vinegar (1 cup)
2 Tbls brown sugar (1 1/2 cups)
1 tsp prepared mustard (4 Tbls)
1 Tbls chili powder (2 1/2 Tbls)
Brown beef,onions,celery and bell peppers- pour off grease then add rest of ingredients and simmer.
