Ingredients
1 teaspoon extra-virgin olive oil, plus more, if needed
4 slices Canadian bacon
2 large eggs
Coarse salt and freshly ground pepper
Mayonnaise, for spreading
4 slices brioche or white Pullman bread, lightly toasted
2 Campari tomatoes, thinly sliced
1 cup packed watercress sprigs, tough stems removed
Preparation
Heat oil in a large cast-iron or nonstick skillet over medium-high. Add bacon in a single layer and cook, flipping once, until warmed through, 2 to 3 minutes. Transfer to a plate; cover to keep warm.
Return skillet to medium-high (add more oil if necessary). Crack eggs into skillet, season with salt and pepper, and fry until whites are set but yolks are still runny, 3 to 4 minutes.
Spread mayonnaise onto bread; divide bacon and tomatoes between slices. Season tomatoes with salt and pepper. Top with watercress, eggs, and remaining bread slices.
