Preheat oven to 350°F (175°C).
In a large oven-safe skillet over medium heat, add the ground beef, red bell pepper strips, green bell pepper strips, and minced garlic. Cook for 8-10 minutes until browned.
Reduce the heat to low. Add the salt, black pepper, Italian seasoning, and paprika; stir to incorporate. Stir in the cauliflower rice until evenly distributed.
Top the mixture evenly with provolone cheese slices, ensuring full coverage.
Bake for 10-12 minutes, or until the cheese is completely melted and bubbly.
Remove from the oven and let sit for 5-10 minutes before serving. Garnish with fresh parsley if desired.
