Prepare pasta according to package instructions. I toss with a little olive oil to prevent the pasta from sticking together.
Add oil over medium high heat and cook shrimp on each side 2 minutes or so and remove from pan. Next cook steak approximately 1-2 minutes on each side. Remove from pan. Add in bell peppers and onions, cooking 4-5 minutes until tender. Add shrimp and steak back in and follow instructions on the fajitas seasoning packet.
Make sauce by adding heavy cream and cream cheese over medium heat. Once incorporated, add in salt, pepper, oregano, garlic powder, onion powder and chili powder. Once slightly bubbling, slowly whisk in cheese and remove from heat. Add in pasta and fajitas. Enjoy!
