Cook pasta according to al dente directions, about 8 minutes. Once done, drain and run cold water over the noodles. This will stop the noodles from cooking.
While the noodles are cooking, cook bacon until crispy, but not burnt. Chop into small pieces.
In a large bowl, add the noodles, bacon, onion, tomatoes, olives and shredded cheese.
Using a glass measuring cup or small bowl, add the ranch dip, garlic powder, pepper and mix. Mix until creamy.
Pour over pasta and mix well to combine. Cover and refrigerate minimum 1 hour or overnight.
Enjoy!
