Place the cut kale into a large bowl. Whisk the dressing together and toss with the kale until evenly coated. If you are using regular lettuce, keep the dressing separate until just before serving. Cover with plastic wrap and refrigerate for at least 30 minutes. Store lettuce or baby spinach and olives if using in fridge until ready to toss with salad just before serving. Fry bacon in batches until crunchy, chop into bite sizes pieces and set aside to drain on paper plate. Drain a bit of the bacon grease off, reserving some in pan. Cook the tomatoes for 3 minutes over high heat in bacon grease, or until beginning to soften and the juices are starting to come out. Remove to a bowl, with juices. Once you are ready to serve the salad, toss lettuce or spinach and olives with the kale, making sure everything is now covered in dressing. Add 3/4 of the bacon and the tomatoes and toss again. Serve with the rest of the bacon and some freshly cracked black pepper.
