01 -  Preheat oven to 350°F. Grease and line an 8x4-inch loaf pan with parchment paper. 
 02 -  In a large bowl, whisk together all-purpose flour, baking powder, baking soda, sea salt, and black pepper until evenly combined. 
 03 -  In a separate bowl, whisk eggs, whole milk, and melted unsalted butter until smooth. 
 04 -  Add the wet mixture to the dry ingredients and stir gently until just combined. Do not overmix. 
 05 -  Fold in snap peas, grated cheddar, and chives until evenly distributed through the batter. 
 06 -  Pour batter into prepared pan and smooth the surface. Bake for 35 to 40 minutes, until a toothpick inserted in the center comes out clean and top is golden brown. 
 07 -  Let loaf cool in the pan for 10 minutes before transferring to a wire rack. Allow to cool completely before slicing.
