1. Bring a large pot of salted water to a boil. Add penne and cook until al dente, following package instructions. Drain and set aside.

2. Toss steak cubes with olive oil, Cajun seasoning, salt, and pepper. Heat a skillet over medium-high heat and sear beef in batches until browned and cooked to preferred doneness. Remove and keep warm.

3. In a saucepan, melt butter over medium heat. Add heavy cream and bring to a gentle simmer. Stir in Velveeta Four-Cheese until fully melted and smooth.

4. Add cooked penne to the cheese sauce, tossing to coat evenly.

5. Serve pasta alongside Cajun beef bites. Garnish with extra Cajun seasoning or fresh herbs if desired.
