Why didn't he just make alfredo sauce? Alfredo sauce is easy af if you use cream cheese in it. I don't even use a recipe, I just whack it together.
1 stick (1/2 cup) butter
1 bar cream cheese (I think they're 6 or 8 0z., just the standard Philly)
2 cups of milk
1 cup grated parmesan (NOT the canned Kraft stuff, REAL parmesan)
Melt the butter first, then tear off knobs of the cream cheese and melt them in the butter until they start to smear. Add the milk, whisk the fuck out of it until it's smooth and hot, and slowly add the parmesan, a little at a time, and keep whisking it in until it's smooth and the parmesan is dissolved. Your basic sauce is done.
Then add in your preferred spices and optional proteins or other add-ins. I prefer pepper, parsley, and a half tsp. of garlic for the spices. Cracked red pepper can also be good if you use a light hand. you can really use any spices you want to customize this sauce; just go easy because it has a delicate flavor and you don't want to overwhelm it.
Of course cooked chopped chicken is obvious in alfredo, but it's great over a sliced fried chicken cutlet as well. Shrimp or bacon are always good. Cooked broccoli, bell pepper, or corn work pretty well. I used jalapeño once, and imho it was too strong but the guests really liked it. Sky's the limit here, anything that goes good with cheese will probably be good in alfredo sauce.
Finally, stir in your cooked pasta, serve salad and garlic bread on the side, bam good dinner.
