Cook your pasta according to the package instructions.
While the pasta is cooking, cook your bacon as desired. Once done, chop it up into small pieces.
Once your pasta has cooked, drain all the water off and add the pasta to a large bowl. Add the chopped up bacon, onions (green and red), shredded cheese, salt, and pepper to the pasta bowl. Set this bowl aside.
Now, mix together your ranch dressing and water until fully mixed. Pour this mixture over the pasta bowl and toss until combined.
Enjoy immediately or chill for later.
