In a large pot over medium-high heat, cook diced onion and ground turkey until turkey is browned and onion is tender. Strain out any excess grease.
Pour in the milk, water, bouillon cubes, tomato sauce, Red Hot, and ranch seasoning. Bring to a simmer. Stir in the pasta and cook uncovered for 10–12 minutes, or until pasta is cooked and liquid has reduced down.
Toss in the cream cheese and shredded cheese and stir until melted. Serve immediately.
Notes
I used and calculated the recipe using 99/1 lean ground turkey. If you can only find 93/7 I wouldn't stress about the macro difference because a lot of the fat cooks off and is strained out in this one.
