In a skillet, brown the ground beef over medium heat until fully cooked. Drain excess fat.

Add the diced bell pepper, onion, and garlic to the skillet and sauté for 3-4 minutes until softened.

Transfer the cooked beef and vegetables to the crockpot.

Add the diced tomatoes, vegetable broth, rice, Italian seasoning, salt, and black pepper to the crockpot.

Stir to combine all ingredients.

Cover and cook on low for 4-6 hours or on high for 2-3 hours until the rice is tender.
