Canned Beans: Black beans or kidney beans add protein and texture; rinse them before using to reduce sodium.
Bell Peppers: Choose vibrant red and green peppers for sweetness and color; chop them into bite-sized pieces.
Diced Tomatoes: Use canned diced tomatoes with green chilies for an extra kick of flavor; they add moisture too.
Onion: A medium onion adds depth; sauté until translucent for optimal sweetness.
Cheddar Cheese: Grated sharp cheddar melts beautifully on top, giving that ooey-gooey finish we all crave.
Spices: Chili powder, cumin, salt, and pepper bring everything together; adjust based on your taste preferences.
Olive Oil: A splash of olive oil prevents sticking when browning the meat; use enough to coat your pan.

Let’s Make it Together
Brown the Meat: Start by heating a skillet over medium heat with olive oil. Add ground beef and cook until browned, breaking it apart as it cooks until no longer pink.
Sauté Vegetables: Toss in chopped onions and bell peppers into the skillet. Sauté until onions become translucent and fragrant, which usually takes about 5 minutes.
Add Ingredients to Slow Cooker: Transfer the cooked beef mixture into your slow cooker. Add canned beans, diced tomatoes (with juices), chili powder, cumin, salt, and pepper. Mix everything well.
Cook Low & Slow: Set your slow cooker on low heat for about 6-8 hours or high heat for 3-4 hours. The longer cooking time melds those flavors beautifully together! For more inspiration, check out this helpful cooking tips recipe.
Add Cheese & Serve!: About 30 minutes before serving, sprinkle grated cheddar cheese on top of the casserole. Cover until melted and bubbly—then dig in!
