Pre-heat oven to 375 degrees and lightly grease a 8×3 loaf pan.
In a large mixing bowl, whisk together both flours, baking powder, cayenne, sugar, salt, pepper. Add cheese and stir to evenly distribute.
In a separate medium bowl, mix together milk, oil, egg, green chiles, jalapeño, and bell pepper.
Make a well in the center of the flour/cheese mixture and pour the milk mixture into the center. Gently mix with a spatula, until ingredients are just combined.
Pour batter into a prepared pan and bake for 45-50 minutes, until the top is golden brown. Let cool for about 10 minutes. Remove bread from pan and let cool completely on cooling rack before slicing.
