Step 1: Direct grill your sausages over a medium fire. While your sausages are cooking, grill your baguettes, and whisk your honey and mustard together.
Step 2: Once your sausages are done, place each one in a toasted baguette. Heat a skillet with oil on the grill and fry each egg sunny side up. While the eggs are cooking, brush each sausage with your honey mustard mixture. Place a slice of cheese on top of each. Top each sandwich with a fried egg, season with salt and pepper, and serve immediately.
