Cook the rotini pasta according to the package instructions. Drain and rinse under cold water.
While the pasta cooks, fry the bacon in a skillet until crispy. Remove and crumble.
In a large bowl, combine the cooked pasta, crumbled bacon, halved cherry tomatoes, and chopped romaine lettuce.
In a separate small bowl, mix together the mayonnaise and apple cider vinegar.
Pour the dressing over the pasta mixture and toss to coat evenly.
Season with salt and pepper to taste.
If desired, add chopped chives for an extra burst of flavor.
Chill the salad in the refrigerator for at least 30 minutes before serving.
Give the salad a good toss before serving to redistribute the ingredients.
Serve cold and enjoy your refreshing BLT Pasta Salad!
