01 - Preheat oven to 325°F. Line an 8x8-inch baking pan with parchment paper, leaving overhang for easy removal.
02 - Combine graham cracker crumbs, finely chopped pistachios, melted butter, and honey in a medium bowl. Mix until texture resembles wet sand. Press firmly into pan bottom.
03 - Bake crust for 8 minutes. Remove from oven and let cool slightly.
04 - Beat cream cheese until smooth. Add Greek yogurt, honey, sugar, eggs, vanilla extract, lemon zest, and salt. Mix until fully combined and silky, avoiding overmixing.
05 - Pour filling over cooled crust and smooth top. Bake for 30-32 minutes until center is just set but slightly jiggly.
06 - Cool to room temperature, then refrigerate at least 3 hours or preferably overnight until fully chilled.
07 - Drizzle with warmed honey and sprinkle with roughly chopped pistachios. Slice into 12 bars.
