Preheat your oven to 350°F (175°C) and grease a medium-sized casserole dish with cooking spray or olive oil.
In a large skillet, over medium heat, brown the ground beef. Drain excess grease if necessary.
Add the diced onion and minced garlic to the skillet, cooking until the onion is translucent, about 3-4 minutes.
Stir in the cauliflower rice, cherry tomatoes, Worcestershire sauce, smoked paprika, oregano, salt, and pepper. Cook for another 5 minutes until everything is well combined and heated through.
In a separate bowl, whisk together the cream cheese, eggs, and half of the shredded cheddar cheese until smooth.
Add the beef and vegetable mixture to the cream cheese blend, stirring until fully incorporated.
Pour the mixture into the greased casserole dish, spreading it evenly.
Top the casserole with the remaining shredded cheddar cheese.
Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown.
Remove from the oven and let it cool for a few minutes before serving.
Garnish with fresh parsley for a pop of color and freshness.
