Sauté Onion and Garlic:

In a large skillet, heat olive oil over medium heat. Add diced onion and minced garlic, sautéing until softened and fragrant, about 3 minutes.

Brown Ground Beef:

Add ground beef to the skillet. Cook, breaking it apart with a spoon, until browned and cooked through. Drain excess fat if necessary.

Add Cabbage and Seasonings:

Stir in chopped cabbage, bell pepper (if using), paprika, chili flakes, salt, and pepper. Cook, stirring occasionally, until cabbage begins to soften, about 5 minutes.

Simmer:

Cover the skillet and reduce heat to low. Let it simmer for an additional 10–15 minutes, or until cabbage is tender and flavors are well combined.

Serve:

Taste and adjust seasoning if needed. Serve hot as a standalone meal or with your choice of sides.
