Combine the flour, baking powder, sugar, and salt in a bowl. Cut in the butter with a fork or knife until the flour is in pea-sized pieces. Mix in the egg and ¼ cup milk. Mix together until it forms a dough and add more milk if needed. Divide into 6 pieces .
In a large skillet, heat oil to medium-high heat. Once the oil is hot, fry the bannock until golden brown, about 3 minutes. Flip and fry the other side until golden brown. Set aside and keep warm until ready to use.
Mix together the pork or sausage, maple syrup, ground pepper and salt. Form into six ¼” thick patties. Using the same skillet as the bannock, cook the sausage patties until brown and caramelized on both sides. Keep warm until you assemble the sandwiches.
Again, using the same skillet, fry your as desired. We prefer over-easy eggs but scrambled or sunny side up is a great alternative.
Assemble the sandwiches by cutting the bannock in half. Spread with dijon mustard. Place an egg on the bottom, then sausage, and 2-3 slices of Avonlea Clothbound Cheddar Cheese. Place in broiler or covered skillet until the cheese melts. Garnish with greens of your choice.
