BLT Pasta Salad

Ingredients

 1 (16 ounce) package medium seashell pasta
1 pound sliced bacon
1 1/2 cups light Ranch-style salad dressing or Poppy Seed Dressing
1 small onion, chopped
2 tomatoes, chopped 

  Chopped Romain Lettuce (add desired amount)

Directions

Bring a large pot of lightly salted water to a boil. Add the pasta, and cook until tender, about 8 minutes.Drain,     and rinse under cold water to cool.  Meanwhile, cook the bacon in a large deep skillet over medium-high heat until browned and crisp. Remove from the pan and drain on paper towels.  In a large bowl, stir together the Ranch dressing, onion, and tomatoes. Mix in the cooled pasta. The pasta will absorb some of the dressing, so don't worry if it seems like too much. Refrigerate for several hours or overnight. Crumble bacon and add chopped lettuce over the top just before serving.
