Preheat oven to 350 degrees fahrenheit and line a baking sheet with parchment paper or a silicone baking mat.
In a large bowl mix bacon, 2 eggs, cheese (not parmesan), parsley, milk and whole wheat flour by hand until well combined.
Once dough is well mixed roll into 2 inch balls. Use the palms of your hands and roll the ball into a rope as long as you can, it's best to roll from the inside out, and then shape into a pretzel.
Brush tops with remaining egg and sprinkle with grated parmesan.
Bake for 15 minutes, cool and refrigerate.
Makes 1/2 dozen pretzels.
