Cook the bacon according to package directions until crisp and crumble or dice into small pieces. Note: I like to bake my bacon in the oven on a baking sheet at 400 for around 15-16 minutes (cooking time may vary). Set aside on paper towels.

Pre-heat the oven to 350 and lightly mist a 2 QT baking dish with cooking spray. Combine the cream cheese, sour cream, cheddar, Mozzarella, mustard, Italian seasoning, garlic powder, ¼ cup of the crumbled bacon (reserve the rest for step 3), salt and pepper in a large mixing bowl and stir together until thoroughly combined (you can also use an electric mixer to save time and arm strength). Transfer the mixture to the prepared baking dish and spread evenly across the bottom. Bake in the oven for 25-30 minutes.

Remove the dish from the oven and sprinkle with the remaining bacon crumbles, the diced tomatoes and the shredded lettuce. Serve hot.
