Prep your ingredients. Dice the onion and bell pepper, chop the broccoli small so it cooks quickly, and mince the garlic. If using eggs, cook and peel them now.
Brown the beef. Heat 2 tablespoons oil in a large skillet over medium-high.
Add onion and cook 2–3 minutes until softened. Add garlic and stir 30 seconds. Add ground beef, breaking it up with a spatula.
Season with salt and pepper. Cook until browned, about 6–8 minutes.
Season the beef. Stir in coconut aminos, tomato paste, smoked paprika, cumin, and chili flakes. Cook 2–3 minutes to coat and slightly reduce.
Taste and adjust salt, pepper, or heat.
Sauté the veggies. In a second skillet, heat 1 tablespoon oil over medium. Add broccoli and bell pepper. Season lightly with salt and pepper.
Cook 4–5 minutes until crisp-tender; remove and set aside.
Cook the cauliflower rice. In the same skillet, add the cauliflower rice with a pinch of salt and pepper. Cook 4–6 minutes, stirring, until just tender and steam has mostly evaporated. Don’t overcook—it should stay a bit firm.
Make the sauce. In a small bowl, whisk yogurt (or sour cream), mayo, lemon juice, Dijon, garlic powder, salt, and pepper until smooth.
Thin with a splash of water if you want it drizzly.
Assemble the bowls. Divide cauliflower rice between 4–5 meal prep containers. Top with seasoned beef, then add the sautéed broccoli and peppers to the side. Add a halved egg to each bowl if using.
Finish with sauce and herbs. Spoon sauce into small lidded cups to keep separate, or drizzle lightly now and save extra for serving.
Top bowls with chopped cilantro or green onions if you like.
