1. Preheat oven to 400°F (200°C). Generously coat large baking sheet with cooking spray and place waffles in single layer.
2. In glass measuring cup, whisk together eggs and pepper; pour evenly over each waffle, spreading to fill cavities. Bake for about 15 minutes or until egg is set and waffles are crisp.
3. Maple-Mustard Mayo: Meanwhile, in small bowl, combine mayonnaise, maple syrup and mustard; set aside.
4. Top 4 waffles evenly with tomato, bacon and cheese. Return to oven until cheese melts, about 1 minute. Top cheese with salad greens and drizzle with maple-mustard mayo. Top with remaining 4 waffles, egg side down. Serve immediately with additional maple-mustard mayo, if desired.
Tip: Substitute bacon with ham, cooked peameal or back bacon. Pre-made bacon makes it extra fast and easy to prepare.
Tip: Substitute cheddar cheese with your favourite cheese.
Tip: Use home-made waffles for an extra special touch; make ahead of time and freeze for the recipe.
