  • 4 cups sweet potatoes cut into 1 inch cubes; see note 1
  • 11 oz can of corn 341 mL; drained
  • 19 oz can black beans 540 mL; drained and rinsed
  • 19 oz can diced tomatoes 540mL; including juices
  • 1 cup red onion diced
  • 1 teaspoon salt
  • 2 tablespoons cumin
  • 1 tablespoon chili powder
  • 4-5 cups stock vegetable or chicken
  • cup quinoa uncooked

After Cooking

  • 2 tablespoons lime juice
  • additional salt start with ¼ teaspoon


  • Place all ingredients into the insert of a 5 or 6 quart slow cooker. This makes a big batch and your slow cooker will be quite full.
  • Cook on low for 6 hours.
  • Add the lime juice and additional salt if necessary. Serve with bread, cheese or yogurt.



1- roughly 1 medium-sized sweet potatoes or 2-3 small ones
To cook in the Instant Pot, reduce the quinoa to ½ cup
Cook 8 min with 10 min natural pressure release (be very careful when releasing the pressure)
The 6 quart was quite full so it might be better cooked in an 8 quart IP
  • fridge- portion out into meal prep containers or store in one larger container. Store in the fridge for up to 4 days.
  • freezer- portion out into glass or plastic freezer jars. Leave ¼ of the jar empty to account for expansion, and leave lids off until fully frozen. Freeze for up to 3 months.
  • Heat individual portions in the microwave until steaming hot.
  • Heat larger portions on the stove over medium heat. Stir occasionally for 15-20 minutes, or until warmed through.
Crockpot freezer meal
Freeze before cooking for an easy 'dump and go' meal:
  1. Assemble all ingredients (except for the quinoa) in a gallon-sized freezer bag, reusable silicone bag, or meal prep container.
  2. Squeeze out as much air as possible.
  3. Freeze flat for up to 3 months.
  4. Thaw completely, dump into the slow cooker, stir in the quinoa, and cook.
