  • 2 Bell peppers, sliced
  • 1 Carrot, julienned

Liquid and Seasonings

  • 200 mL Tomato sauce
  • ¼ cup Broth (bone broth recommended)
  • 1 tablespoon Chili powder
  • 1.5 tablespoons Cumin
  • ½ teaspoon Paprika
  • 1 teaspoon Salt
  • 2 teaspoons Garlic powder

Instructions

  1. Prepare Vegetables: Slice the bell peppers into strips and julienne the carrot. If using, slice the sweet onion. Set these aside.
  2. Combine Ingredients in Slow Cooker: Place the beef strips into the slow cooker, followed by the prepared vegetables positioned on top of the meat.
  3. Add Liquids: Pour the broth and tomato sauce evenly over the beef and vegetables to provide moisture and flavor during cooking.
  4. Season: Mix together the chili powder, cumin, paprika, salt, and garlic powder to create the fajita seasoning. Sprinkle it evenly over the ingredients in the slow cooker.

Notes

  • Almost any cut of beef will work; stir fry strips or flank steak strips are preferred.
  • No need to lock the lid tightly to let some steam escape during cooking.
  • Cook time may vary depending on the size of your slow cooker; adjust accordingly.
  • You can use any kind of broth, but bone broth powder adds a healthy boost and ease of use.
  • Nutrition values are estimates and should be verified independently if needed.
