Cook the bacon: In a skillet over medium heat, cook bacon until crisp. Transfer to a paper towel–lined plate. Once cool, crumble.
Reserve 1 to 2 teaspoons of bacon drippings if you like for extra flavor.
Prep the chicken: Shred or dice the cooked chicken into bite-size pieces. Aim for uniform size so every bite feels balanced.
Make the dressing: In a large bowl, whisk together mayonnaise, Greek yogurt, Dijon, lemon juice, garlic, smoked paprika, and a pinch of salt and pepper. If using, whisk in a little reserved bacon fat for richness.
Fold in the chicken: Add the chicken to the bowl and stir until well coated.
Taste and adjust with more lemon, salt, or pepper.
Add BLT elements: Gently fold in the crumbled bacon, tomatoes, and red onion. Save a little bacon for topping if you want a nice finish.
Stir in greens last: Fold in the chopped lettuce and chives. If using avocado, add it now and mix gently so it stays in chunks.
Chill briefly: Cover and refrigerate for 15–20 minutes to let the flavors settle.
This step deepens the taste and firms up the texture.
Serve: Spoon onto toasted sourdough, tuck into lettuce wraps, roll in a tortilla, or serve over mixed greens. Finish with a grind of black pepper and a squeeze of lemon.
