Ranch Mac 'n' Cheese

1 package (16 ounces) elbow macaroni
1 cup 2% milk
2 tablespoons butter
4 1/2 teaspoons ranch salad dressing mix
1 teaspoon garlic-pepper blend
1 teaspoon lemon-pepper blend
1/2 teaspoon garlic powder
1 cup shredded Monterey Jack cheese
1 cup shredded Colby cheese
1 cup reduced-fat sour cream
1/2 cup crushed saltines
1/3 cup grated Parmesan cheese

Cook the macaroni according to package directions. Meanwhile, in a Dutch oven, combine the milk, butter, dressing mix and seasonings, heat through. Stir in the Monterey Jack and Colby cheeses until melted. Stir in sour cream.

Drain macaroni, stir into cheese sauce with the saltines.  Sprinkle with Parmesan cheese.

Note: I forgot to add the sour cream (shouldn't cook when I'm not feeling well). I also did not add the saltines because I felt like I didn't really need them. Tasted yummy without both ingredients.
