Toast the pecans: In a dry skillet over medium heat, toast pecans for 3 to 5 minutes until fragrant. Cool completely, then chop.
This deepens flavor and keeps them crisp.
Mix the dressing: In a large bowl, whisk mayonnaise, yogurt, Dijon, lemon juice, honey, herbs, salt, and pepper. Aim for a creamy but not runny texture.
Fold in the add-ins: Add chicken, celery, green onion, dried cranberries, and pecans. Gently fold until everything is coated.
Taste and adjust salt, pepper, and lemon.
Chill the salad: Cover and refrigerate for at least 30 minutes. This lets flavors meld and helps the mixture set for easier sandwich assembly.
Prep the bread: If making tea sandwiches, choose thin, soft slices. Lightly spread softened butter on one side of each slice to prevent sogginess.
Assemble: Spread a generous layer of chicken salad on the unbuttered side of half the slices.
Add microgreens or cucumber if using. Top with remaining slices, buttered side down.
Trim and cut: Use a sharp serrated knife to trim crusts for a classic tea look. Cut each sandwich into neat halves or quarters—rectangles or triangles work well.
Serve: Arrange on a platter.
For a polished touch, garnish with a few extra cranberries and chopped pecans around the edges.
