Brown the meat. Heat oil in a large skillet over medium-high.
Add ground beef and break it up. Cook until browned with small crispy bits, about 6–8 minutes. Drain excess fat if needed.
Add aromatics. Stir in onion, bell peppers, garlic, and jalapeño.
Cook 3–4 minutes until softened and fragrant.
Season it. Sprinkle in the spice mix, tomato paste, and green chiles. Stir well to coat the meat and veggies. Cook 1–2 minutes to bloom the spices.
Load the slow cooker. Add the beef mixture to your Crockpot.
Stir in cauliflower rice and beef broth. Mix until evenly combined.
Slow cook. Cover and cook on Low for 4–5 hours or on High for 2–3 hours. Stir once halfway if you can.
Finish creamy. Stir in cream cheese until fully melted and smooth.
Taste and adjust salt or heat.
Add the cheese. Sprinkle shredded cheese over the top. Cover and cook another 10–15 minutes until melted and bubbly.
Garnish and serve. Top with cilantro and green onions. Scoop into bowls and finish with sour cream, avocado, and a squeeze of lime.
