Cook the pasta according to package instructions until al dente.
While the pasta is cooking, chop the roasted peppers and fresh parsley. (If you don't have the bacon pre-cooked already, go ahead cook until crispy)
In a medium bowl, (the bowl you will be making the pasta salad in) add and whisk together the mayo, sriracha sauce, lemon juice, pickle juice, granulated garlic, salt, pepper, paprika and onion powder to make the dressing.
Once the pasta is done cooking, drain the cooked pasta and rinse it under cold water to stop the cooking process while stirring for about 30 seconds.
Then add the pasta, pepper, bacon, and fresh parsley to the bowl with the dressing in give it a good stir. (If you're chilling the pasta salad for a few hours, I'd wait to add the bacon and parsley when you are ready to serve. It'll just look fresher that way.)
Chill the pasta salad in the refrigerator for about 1 hour. (If you don't have time to wait you can enjoy the salad immediately.)
Once you're ready to serve the pasta salad, go ahead and add the chopped parsley and bacon.
