Toast your base: Lightly toast your bread, English muffin, or bagel for structure and crunch. If using a tortilla, warm it in a skillet to make it pliable.
Prep a quick sauce: Stir 1 tablespoon Greek yogurt with 1 teaspoon Dijon mustard and a pinch of salt and pepper. This adds creaminess and protein without heaviness.
Cook the eggs your way: Soft scramble: Whisk 1 whole egg + 2 egg whites, cook over low heat with a little oil, stirring until just set.
Fried: Cook in a nonstick skillet, flipping if you like it over-easy or over-medium.
Folded omelet: Pour beaten eggs into a skillet, let set, add cheese, fold into thirds for a neat sandwich layer.
Add cheese to melt: Place cheese on the eggs during the last 30–60 seconds so it melts without overcooking the eggs.
Layer thoughtfully: Spread your sauce on the toasted bread.
Add greens, then your egg-and-cheese, then lean meat or smoked salmon if using. Top with tomatoes, avocado, or onions.
Season smartly: Add a pinch of salt, black pepper, and, if you like, chili flakes or everything bagel seasoning for a quick flavor boost.
Press and serve: Close the sandwich and gently press. For a crispy exterior, return it to the skillet and toast each side for 1–2 minutes.
