- Preheat oven to 400°. Invert a muffin tin upside down onto a large rimmed baking sheet.
- Cut 8 slices of bacon in half crosswise. Lay two of the halved strips onto an inverted muffin tin cup in the shape of a cross. Weave two more half pieces on both sides to create a mini weave. Wrap the entire cup with a whole slice of bacon. Repeat to make three more cups. Bake until crispy, about 20 minutes. Let cool for at least 15 minutes.
- Make dressing: In a medium bowl, whisk together Greek yogurt, lemon juice and chives and season with salt and pepper. Add tomatoes and lettuce and toss to coat.
- Remove bacon cups from muffin tin and fill with dressed lettuce and tomatoes. Garnish with more chives and serve.
