- 1 green bell pepper, diced

- 14.5-ounce can diced tomatoes with green chilies (undrained)
- 1 1/2 cups frozen corn
- 2 teaspoons minced garlic
- 1/2 teaspoon chili powder
- 1 teaspoon Worcestershire sauce
- Pinch cayenne pepper or a few drops of hot sauce (optional)
- 1/2 to 1 cup shredded cheddar, Colby Jack, or taco blend cheese
- Fresh cilantro and sour cream for garnish (optional)

Equipment Needed
- 6-quart slow cooker (Crock-Pot)
- Large skillet for browning meat and veggies
- Cutting board and knives
Step-by-Step Instructions
Step 1: Brown the Meat and Veggies
Heat olive oil in a large skillet over medium-high heat. Add ground beef (or sausage), onions, and diced bell peppers. Season with salt and black pepper. Brown the meat until fully cooked and the veggies are softened, about 6-7 minutes. Drain excess fat.
Step 2: Layer Ingredients in Slow Cooker
Spray the inside of a 6-quart slow cooker with nonstick cooking spray. Place half the potatoes in the bottom, then layer the browned meat and veggies over top. Add the drained kidney beans, frozen corn, and diced tomatoes with green chilies.
Step 3: Add Seasonings and Mix
In a small bowl, combine minced garlic, chili powder, Worcestershire sauce, and cayenne pepper or hot sauce (if using). Sprinkle the seasoning mixture over the slow cooker ingredients. Gently stir to combine and then press everything into an even layer.
Step 4: Cook Low and Slow
Cover and cook on LOW for 4-6 hours or on HIGH for 2-3 hours until potatoes are tender when pierced with a fork.
Step 5: Add Cheese and Finish Cooking
Sprinkle the shredded cheese evenly over the top. Cover and continue cooking for another 5-10 minutes, or until the cheese melts.
Step 6: Garnish and Serve
Sprinkle with fresh cilantro and serve with a dollop of sour cream if desired. Enjoy warm!
