BLT Pasta Salad

We had this amazing salad for lunch the other day and it was fantastic. I would recommend it to anyone, especially bacon lovers.
My mother got this recipe from Food Network.

BLT Pasta Salad

• 12 ounces corkscrew-shaped pasta (We used Penne)
  
• 1/2 cup milk
• 12 ounces lean bacon
• 3 medium ripe tomatoes, cut into chunks
• 1 tablespoon chopped fresh thyme
• 1 clove garlic, minced
• Kosher salt and freshly ground pepper
• 1/2 cup mayonnaise
• 1/4 cup sour cream
• 4 tablespoons chopped chives or scallion greens
• 5 heads Bibb lettuce, quartered, or 5 cups chopped romaine hearts (We didn't use near this amount but I think we should have used more)
  

Cook the pasta in a large pot of salted boiling water as the label directs. Drain and toss with the milk in a large bowl; set aside.

Meanwhile, cook the bacon in a large skillet over medium-high heat until crisp. Drain on paper towels. Discard all but 3 tablespoons drippings from the pan. Add the tomatoes, thyme and garlic to the pan and toss until warmed through; season with salt and pepper. Crumble the bacon into bite-size pieces; set aside 1/4 cup for garnish. Toss the remaining bacon and the tomato mixture with the pasta.

Mix the mayonnaise, sour cream and 3 tablespoons chives with the pasta until evenly combined. Season with salt and pepper. Add the lettuce; toss again to coat. Garnish with the reserved bacon and the remaining 1 tablespoon chives. Serve at room temperature.
