In a large bowl, whisk honey, eggs and 2 cups buttermilk. Chill.
Remove dry mixture from refrigerator. Add broccoli, Cheddar, tomatoes, green onions, garlic and almonds. Toss. Remove wet mixture from refrigerator, and add dry mixture to it, combining with hands until a soft, slightly sticky dough forms, adding more buttermilk if mixture is too dry. Chill dough 30 minutes to 2 hours in refrigerator.
To prepare glaze: Preheat oven to 350 degrees and line baking sheets with parchment paper. In a medium bowl, beat together 1 egg, 2 tablespoons buttermilk and honey, set aside.
On a well-floured work surface, divide dough into three portions. Pat each portion of dough into a circle about 2 inches thick, and cut into 4 wedges. Transfer scones to prepared baking sheets and brush with glaze. Bake until golden brown, about 30 minutes. Remove from oven, cool and serve.
