In a large skillet over medium heat, melt the butter and oil.
Add the halved cherry tomatoes, steak seasoning, and garlic powder. Cook for 8–10 minutes, stirring occasionally, until the tomatoes start to break down and get saucy.
Simmer for 5 minutes, until the sauce has thickened a little bit. It will be pretty liquidy, but that's okay.
Add the drained pasta, baked meatballs, parmesan, fresh basil, and lemon juice to the pan and toss everything together until coated and glossy.
Serve the pasta warm.
